Atoning — Kelley Armstrong

A Darkest Powers/Darkness Rising novella.

Chloe and Derek have adjusted to life in Badger Lake. It's not perfect, but it's safe and they're learning the skills they'll need when it comes time to make a decision about their futures. They're comfortable and they're settled . . . until a weekend camping trip with Maya and Daniel reunites them with someone they thought they'd left in the past. Someone Derek really hoped they'd left in the past, because as much as this former friend might want to atone for past mistakes, she's nothing but trouble.
