Soulstone (Immortalis Vampire Series Book 4) Kindle Edition

4.6 4.6 out of 5 stars 76 ratings

Second Edition - 2015

It’s a desperate time for rookie vampire Alyssa, and her sanity is hanging by a slender thread. Her clan is still reeling from the monumental battle with Aniketos; a battle that claimed the body of Lysander, her sire and lover, and trapped his spirit in a mysterious crystal. A Soulstone.

Unfortunately, no amount of magic has been able to release Lysander’s spirit, and the stone is starting to fade. Weeks of effort have proved futile. Her clan, the Peregrinus, have all but given up hope. Only Alyssa still believes her lover can be released. In despair, Alyssa begs the help of the local witch coven, and unwittingly exposes the supernaturals of Boston to unwanted attention from the Acta Sanctorum.

The Saints converge on the city and begin their cleansing crusade to rid the world of all things “Unnatural.” In the middle of an all-out war, but no closer to a solution to the dying stone, Alyssa is left with an unenviable choice: save her mate, or save her clan.

Second Edition - If your copy does not have a 2015 copyright date you are reading an old version.Books in the Immortalis Series:

Becoming a vampire is easy. Living with the condition... that's the hard part. Join Alyssa as she stumbles through the world of the "Unnatural."

Book 1: Carpe Noctem - Newbie vampire Alyssa never asked for this life, but now it's all she has. Rescued from death by Lysander, the aloof and sexy leader of the Peregrinus vampire clan, she's barely cut her teeth before she becomes a target. Kallisto, an ancient and vindictive vampire queen - and Lysander's old mate - wants nothing less than final death for her former lover and his new toy. She's not above letting the Acta Sanctorum, and its greatest vampire hunter, Santino, know exactly where the clan can be found.With no time to mourn her old life, Alyssa's survival depends on her new family. She will have to stand alongside Lysander and fight against two enemies who will stop at nothing to destroy them.

Book 2: Hunters & Prey - Rule number one: humans and vampires don't co-exist. One is the hunter and one is the prey. Simple, right? Not for newly-turned vampire Alyssa. A surprise confrontation with Santino Vitale, the Acta Sanctorum's most fearsome hunter, sends her fleeing back to the world she once knew, and Fallon, the human friend she's missed more than anything. Now she has some explaining to do. However, that will have to wait. With the Acta Sanctorum hot on their heels, staying alive is more important than educating a human on the finer points of bloodlust.

Book 3: Pandora's Box - After a few months as a vampire, Alyssa thought she'd learned all she needed to know about the supernatural world. But her confidence is shattered by the delivery of a mysterious package - a Pandora's Box. Seemingly innocuous, the box is in reality an ancient prison, generated by a magic more powerful than anyone in her clan has ever known. But what manner of evil could need such force to contain it? When the box is opened, the sinister creature within is released, and only supernatural blood will satiate its thirst. The clan soon learns how it feels when the hunter becomes the hunted.

Book 4: Soulstone - It's a desperate time for rookie vampire Alyssa, and her sanity is hanging by a slender thread. Her clan is still reeling from the monumental battle with Aniketos; a battle that claimed the body of Lysander, her sire and lover, and trapped his spirit in a mysterious crystal. A Soulstone. Unfortunately, no amount of magic has been able to release Lysander's spirit, and the stone is starting to fade. Weeks of effort have proved futile. Her clan, the Peregrinus, have all but given up hope. Only Alyssa still believes her lover can be released. In despair, Alyssa begs the help of the local witch coven, and unwittingly exposes the supernaturals of Boston to unwanted attention from the Acta Sanctorum. The Saints converge on the city and begin their cleansing crusade to rid the world of all things "Unnatural." In the middle of an all-out war, but no closer to a solution to the dying stone, Alyssa is left with an unenviable choice: save her mate, or save her clan.

Companion Novellas
Moonlight
Good girls don't wear fur, or fight over men, and they certainly don't run around naked, howling at the moon. But then, no-one ever called Fallon a good girl. As a human
unofficially mated to an Alpha werewolf, Fallon is being pressured to "become"...or be gone. Her mate Aiden, the interim leader of the Olde Town Pack, is in a position that demands he either choose a wolf mate...or leave the pack forever. No matter how hot the sex with Fallon is, he can't ignore centuries of tradition. Become a wolf or not. If only the choice were that simple. Fallon's options are further clouded by the overt presence of other females desperate to be the Alpha's mate. And when these bitches get serious, it's not just claws that come out. If Fallon wants to keep her man and take the title she'll have to exert a little dominance of her own.

Dark Salvation
A gathering storm of violence is on the horizon. Whispered threats of the Acta Sanctorum's return have the supernatural world abuzz. Only recently aware of the other world hidden behind our own, Kitara Vanders has barely scratched the surface of what being supernatural truly means. A special woman in her own right, she possesses unique telepathic abilities, gifts that have recently come under the scrutiny of the Acta Sanctorum, a fanatical organization whose mission is to cleanse the world of anything supernatural. Targeted, and marked for death, Kitara's only hope lies with the lethally seductive yet emotionally scarred warrior, Nicholas.
Knowing full well the atrocities the Acta Sanctorum is capable of, Nicholas is all too eager for the battle to begin. Fueled by pain and rage from the loss of his mate, he's itching for a fight, but one thing stands in his way, Kitara: a beautiful dark-haired woman with unique psychic abilities and an unusual link to the Saints. Despite his resolve to remain focused on his mission, a purely physical relationship binds them together in a way neither of them expected. And when her life hangs in the balance, Nicholas finds his own is teetering on the edge too.

    Given how I've given positive reviews on the previous works, I think it's safe for anyone to come to the conclusion that I'm a fan of this series. Once again, Katie Salidas did not disappoint.

    Soulstone was good. It was not as good as Pandora's Box in my opinion, but I liked it at least as much as Immortalis Carpe Noctem. I'm really not sure what caused this book to not be as good as the last one. It was still very interesting and kept me on the edge of my seat.

    All the same, I am looking forward to similar works from Katie Salidas. She has definitely become one of my favorite authors recently.

    They just keep getting better and better! I agree that this story shows how emotionally strong and determined Alyssa has become. She really shines in this one.I have liked Nicholas's character from the beginning of this series and I like him even more now. Despite his hurt he did all he could to help Alyssa and Lysander. I am wondering if he will ever find someone else. For me it is near impossible for a previous bad guy to redeem himself. Not only has Santino managed to redeem himself to me but I was actually upset with what the wolves did. They had good reasons but I was so mad at them for a short while. Then felt badly for the wolves towards the end. My point is that for me this shows how good of a story teller Katie Salidas is. I hope there will be more books in this series. I also hope that Nicholas will get his own book since he is such a strong character.

    I loved that both Vampire and Wolf finally worked together for the same goal. Full of up and down emotions. As always, full of action. A romantic novel but more like an action mystery book. Each book gets better than the last. Witches, too. They were a surprise.

I found I was turning through every page in no time because Everything about the book was entertaining. The dynamic with the characters in the book are fantastic.

    Good book, interesting twist and turns with the bad guys. Nice twist on Santinio working with the clan and werewolves. Shame Connor died how he did but his son is willing to adapt and not see everything so black and white. Lots more action in this book with all the characters learning to work together whether they are vampires, werewolves or witches. Good series so far

    I used to read this series years ago but lost interest. I couldn't remember much of the previous books but I do remember they were better than this one. It is still a good book but I feel I'm getting bored of the vampire genre.
