Summer Davis is a Cipher, a person chosen to help people resolve problems with their loved ones before they die. She’s just gotten her second job when weirder-than-usual things start happening. There seems to be a rift between her and the afterlife, and she’s seeing things she shouldn’t, including people who have already passed on. As she struggles to help her new assignment, Liam, make amends with his incarcerated father, she finds it hard to balance being a high school student, Cipher, and girlfriend. Troy’s been nothing but supportive, but Summer can see her secret weighs on him, and she worries the more she tells him, the sooner he’ll decide he can’t deal with her freaky life. But when a murderer is thrown into the mix, and the girl he killed keeps asking Summer for help, she’ll risk everything to make sure the guy gets what he deserves.
