Forget I Told You by Tanya Chris

His memory’s been erased, but his soul can’t forget its mate.
Jay has a nice wife and a nice life with a nice house and a nice job in the very nice city of Seattle. Except he’s beginning to suspect that none of that is true. If he has a wife, why can’t he remember marrying her? And why does trying to remember make his head hurt?
Deron knows he shouldn’t be in Seattle. Giving into his need to check on the man who once belonged to him could put a complicated cross-agency investigation at risk. All he wants is one little peek. He didn’t expect Jay to recognize him or for the two of them to get shot at on the streets of Seattle.
Jay’s suffering from a case of amnesia only he can cure and is at the heart of a mystery only he can solve. Too bad he doesn’t know any of that. But there’s one thing he does know: Deron. His memory may have been removed, but his soul will never forget its mate. Can he remember everything else in time to save both their lives and possibly an entire country?
