He'll go anywhere and any when to save his daughter

Kin Stewart is an everyday family man: working in IT, trying to keep the spark in his marriage, struggling to connect with his teenage daughter.

But his current life is a far cry from his previous career...as a time-traveling secret agent from over a century in the future.

Stranded in suburban San Francisco since the 1990s after a botched mission, Kin has kept his past hidden from everyone around him, until one afternoon, his "rescue" team arrives--eighteen years too late.

Their mission: return Kin to 2142, where he's been gone only weeks, not years, and where another family is waiting for him. A family he can't remember.

Torn between two lives, Kin's desperate efforts to stay connected to both will threaten to destroy the agency and even history itself. With his daughter's very existence at risk, he will have to take one final trip to save her--even if it means breaking all the rules of time travel in the process.

"Heartfelt and thrilling... Chen's concept is unique, and his characters'] agony is deeply moving. Quick pacing, complex characters, and a fascinating premise."--Publishers Weekly, starred review
