Fifteen-year-old Therese watches her parents die. While in a coma, she meets the twin sons of Hades-Hypnos (the god of sleep) and Thanatos (the god of death). She thinks she's manipulating a dream, not kissing the god of death and totally rocking his world. Than makes a deal with Hades and goes as a mortal to the Upperworld to try and win Therese's heart, but not all the gods are happy. Some give her gifts. Others try to kill her. The deal requires Therese to avenge the death of her parents.
Ten agonizing months have gone by since Therese faced off against her parents' murderer at Mount Olympus, and she suspects Thanatos's absence is meant to send her a message: go on with your life. She tries to return Pete's affections, but when Than shows up to take her hamster's soul, she sees him and becomes infuriated when he says he's "been busy."
