Summer Surrender (Phases Series, Book Six) by Green, Bronwyn

Hollis Chambers came to Michigan’s Upper Peninsula to teach summer school at a small rural high school. She’d planned on hanging out on the shores of Lake Superior, taking walks in the woods and studying the wildlife. She never imagined that she’d meet one man, let alone two, to have a hot summer fling with.

Lynx shifters Daniel Cichosz and Josiah Wilder know a good thing when they see it and they’re fairly certain that the gorgeous, full-figured substitute teacher is just who they’ve been looking for. Hollis surrenders to their seduction, but how will she feel about being mated to shifters, particularly when Daniel’s brother is added to the mix?
