When angels fell from the sky to war with the demons that ravaged Earth, their combined powers infected humanity. Now, the humans are assigned one of two fates: demon gifted or angel blessed. After wings sprout from Brielle's back at her awakening ceremony, she's sure she's an angel-blessed celestial—until she sees black wings and realizes something is terribly wrong. She should be bound for Tainted Academy. That is, until a fallen angel unexpectedly fights for her to be accepted into Fallen Academy, the elite school for those that inhabit Angel City. She's immediately matched with her impossibly handsome celestial teacher Lincoln Grey. Then, the entire school is thrown into chaos when an Abrus demon reveals that he knows Brielle's secret. Now, above all else, Lincoln must fight to protect her—and fight his feelings for her.
