The Broken Places - Mia Sheridan

In this twisted journey into the shadows of the Golden Gate, a detective and an FBI agent must track down the source of an unknown drug, but their attraction and their own secrets keep getting in the way. The streets of San Francisco aren't as sunny as the city pretends they are. Detective Lennon Gray has learned this the hard way, and it’s starting to wear on her.

When a new case plunges her into the depths of the transient community, Lennon must once again face ugly truths about humanity. Her new partner makes things a little easier, though. Agent Ambrose Mars is charming - innocent, somehow, despite his own hard years in the field.

The combination leaves Lennon fascinated and disturbed at the same time, and she’s even more drawn to him for it. As they investigate the hallucinogenic drug that's forcing homeless citizens into bizarre and dangerous role-plays, Lennon and Ambrose find their relationship intensified with every new twist. But when these revelations begin to uncover secrets she wasn’t prepared to know, Lennon will have to decide how much more she can take...

before something important is taken from her.
