She was the best of the best, until her alien masters took away her past.
He was just a police photographer before they attacked San Francisco.
In 24 hours they face infection, decapitation and orbital bombardment. Then things get serious!

“This fast-paced sci-fi thriller satisfies on multiple fronts...Smart, engaging, with a touch of wry wit - a real treat!”

When a human invention accidentally breaks the laws of physics, the aliens hiding amongst us will fight each other to control it. If they can’t win, they will make sure everyone else loses. Permanently.

Fleet Four assigns the legendary Keryapt Zess to uncover which galactic rival thinks Earth is worth fighting over. With a cutting edge Interloper body and the best support team in Labworld Command, there should be nothing on Earth that can stand in her way.

But no plan survives contact with the enemy. There are only two people she can trust - her Shadow back in Fleet Four and a human photographer who was in the right place at the wrong time. Can they help her stay alive long enough to answer the question - who wants us dead?

And what will she do if the answer is “Everyone”?
