A twelve-year-old Roman is about to ruin history.

And he couldn't care less.

Harry and Jett are time travellers. But more than that - they're best friends. After saving the world from time-manipulating Nazis and restoring the past, the boys thought their adventures had ended.

But they've got a new problem - because doors, once opened, seldom stay closed.

And now a boy from Ancient Rome, stranded in time, is determined to learn all of their secrets.

A boy who would do anything to avenge his father.

A boy who would do anything to change his past.

Even if it means erasing the future... 

Join Harry and Jett on another rip-roaring adventure in this millennia-spanning second book in the PARTNERS IN TIME series.

"I swear I wasn't crying - the Princess is a liar. But the rest of the book is fantastic! Best thing I've read in one thousand, five hundred and forty-eight years."

Romulus Augustus, aged 12 - Last Emperor of Rome

"He was definitely crying. Boys can be so silly."

Princess Margaret also aged 12 and not worried about foolish titles.

"I might have cried a little bit, but I don't think anyone saw."

Jett - not quite yet 12 and with no title that he knows of.
