Kalix by Bethanie Loren

The girl who’s anxious, studious, and terrified of the dark gets herself a shadow… What could go wrong?

College was supposed to be a fresh start for Lainey, at least until she began to sense that she was being watched. It felt like someone was lurking in the shadows. Too close. Too silent. No matter where she looked, though, she just couldn’t find where the feeling was coming from.
When a guy she’s never seen before, someone named Kalix, comes into her Chemistry class, everything changes.
He’s tattooed, pierced, and not like anything she’s ever seen herself being attracted to. As a matter of fact, he’s exactly what she tried to steer clear of: trouble.
He’s overly intense, obsessive, and somehow always there when she least expects it.
She should be scared of him, but for some reason, she’s not.
When someone else’s obsession becomes too much, the one she tries to steer clear of is the one person she turns to for help.

The girl who’s always feared the dark is now beginning to crave what’s in it.
