See No Evil - Brotherhood Trilogy, #1

She's a key witness in a murder trial and she's been hidden away in the one place no one will think to look for her-an all boys' boarding school. Christiana's friend has been murdered.and she knows who did it. Now, instead of completing her senior year with the popular crowd, this fashion princess is being forced to hide in a school with exactly zero XX chromosomes. Even worse, she's somehow supposed to act like the jocks walking these halls.
And then she meets the smoking-hot hockey players next door. And it doesn't help that one in particular could unravel her in a heartbeat.and potentially blow her cover. Trey is confused by the pull he feels toward the scrawny new guy. He didn't think he swung that way. But he can't deny the fiery chemistry between them, and no matter how hard he tries to dislike him, he feels oddly protective. an instinct that amplifies when he learns the truth.
Now all that matters is keeping Christiana safe, because a dangerous killer wants her silenced at any cost...
