Hawaii Five Uh-Oh — Z.A. Maxfield

Sarcastic cop Theo Hsu returns home to Hawai'i after realizing he wants more from his life... and also less. He hopes to reconnect with his past and make amends with his mother, who's remarried to a cool, distant man, leaving Theo unsure where he stands.

It doesn't take him long to figure out where he wants to stand, though: right next to his childhood best friend, tattooed detective Koa Palapiti. Theo would like to upgrade their relationship, but Koa is putting out some seriously mixed signals. It's a mystery Theo can't let go, but just as they start to connect, kidnapping, murder, and a deadly game with international stakes get in the way. Koa wants to keep Theo out of it, and if it comes to a choice between him and Koa's partner, Freddie Ortiz, Theo doesn't like his chances.

But even if Koa wants to push him out of the investigation, and his life, Theo still has a few tricks up his sleeve. It'll take all his special gifts, ingenuity, risk-taking, family ties--and even some kinky undercover work--to save the day... and the man he never should've let get away.
