Who do we fall in love with? The person we see, or who they are inside?

Dylan Knox is not the man he was. He may be like no man who ever existed.

Brooke’s old flame doesn’t remember her. Worse, he behaves like different people at any given moment.

A victim of a brain injury? Or an imposter—an assassin targeting Brooke’s boss, the secretary-general of the United Nations?

Dylan’s tale of castaways in time and space is utter fantasy.

Unless it’s too crazy not to be true.

Brooke’s obsessive quest for the truth will shatter her every belief, and leave her with an unthinkable choice: trust, or betrayal.

And falling in love is the last thing she needs.
