Hazardous Things by Beth Bolden

Felix Humphries can’t even remember the first time he crushed on Star Shadow’s drummer, Max McCloud.
It’s been an embarrassingly long time, but he’s still never acted on his feelings. One, because Max is his older brother’s best friend. Two, because Max is also his friend. Three, Max is technically his boss. And four, worst of all, Max is straight.
But when Max unexpectedly needs a caretaker for a few weeks, Felix can’t leave his friend in the lurch. He’s all ready to suffer through being so close but not close enough, when the unexpected happens.
Max isn’t straight after all, and what Max wants is Felix—but only in his bed, not in his heart.
