This is the third and final novel of the Everneath trilogy. Nikki has rescued Jack, and now she just wants to graduate high school, but soon finds her energy drained. Cole had tricked her into feeding on him in the Everneath, so now she is in the process of becoming an everliving. She and Jack decide to fight for her life with everything they have. Unfortunately, if Nikki doesn't feed on Cole every night, she dies. Many awkward situations arise.
Nikki wants to find a way to sever her connection to the Everneath, but she has attracted the attention of the Queen, and the Queen has a reputation for killing any rival for her throne. Can she escape with her life once and for all?
More connections to Persephone and other underworld myths arise. Much more action than the previous two novels. Friendships are strained and enemies are trusted. A fitting end to the series.
