I am posting late since this is the first time I used the internet without worrying about the event I am co-organizing.
Breaking the Spine.
Title: SHADOWSPELL, the second book in the Faeriewalker series
Author: Jenna Black
Publication Date: January 4, 2011
Publisher: St. Martin's Griffin
Synopsis from Goodreads:
The Erlking and his pack of murderous minions have descended upon Avalon. The smoldering and deadly Erlking has his sights set on Dana and her rare Faeriewalker powers—but does he only seek to kill her, or does he have something much darker in mind?
I found the first book a little tame. But that doesn't stop me from wanting to read the sequel!
