Endlessly (Paranormalcy, #3) by Kiersten White

Try as she might, Evie can’t seem to escape her not-so-normal past. And what was supposed to be a blissfully normal school break is ruined when a massive group of paranormals shows up at her house, claiming that Evie is the only one who can protect them from a mysterious, perilous fate.

The deadly war between the faerie courts looms ever closer. The clock is ticking on the entire paranormal world. And its future rests solely in Evie’s hands.

So much for normal.

With a perfect blend of humor and suspense, Endlessly is everything readers could dream of in a conclusion—and the unexpected twists will keep them guessing until the very last page.
