Shadow of the Moon (#4) by Rachel Hawthorne

Hayden has lived among humans, coming back during the summers to be with her own kind. She can sense the emotions of other shifters which is why she hides out. The harvester has been attacking shifters during their first full moon and now it's after her. Daniel is determined to help her, destroy the harvester and be her mate if she'll accept him.

This was a series I stumbled upon by accident but really enjoyed. This fourth book didn't disappoint. The characters are intense but something just grabs your attention. Maybe it's the fantasy element or the fact that the relationships in the book are different than real life. So sad that this was the last in the series.
