Sixteen year old Sophie Bloom is an ordinary girl. She has two BFF's, Hannah and Theo, and a bully--yoga-goddess-Bethany, and a mother who mostly can't be bothered, which is why she lives at her Vancouver boarding school. 
 On Halloween Sophie pulls a laxative prank on the vile Bethany, then sneaks out to ruin Bethany's rendezvous with a mysterious boy, Kai. If only high school hijinks were so simple. Sophie does meet Kai, but instead of humiliating Bethany, the kiss Sophie receives triggers an onslaught of memories from her prior life--as Persephone, goddess of Spring and Fertility. Turns out Kai is really Kyrillos, son of Hades, and Persephone's jilted ex. 
 Kai's about to reclaim his long-lost love when Theo--who is really Prometheus--intercedes, dragging Sophie back to the school grounds. 
 Kai enrolls himself in the school--that's the only way he can get near Sophie/Persephone thanks to Theo's magical wards--but Sophie's not really that keen on him. I mean, he's gorgeous but Sophie's concerned that Kai only wants her for Persephone--and she can't even remember that life. Of course, Bethany's on a mission to win Kai for herself, and the spite is quintessential Mean Girl. 
 Yeah, and you thought your high school romances were complicated! 
 Classmate Cassie spouts earth-shattering prophesy only Persephone can avert--by hooking up with Kai--cementing the weird-factor. Oh, and Sophie develops defensive magic of her own, which is great now that Hades and Zeus have sent their lightning and fireball wielding minions to destroy her. 
 Desperate to reclaim her inner Persephone, Theo takes Sophie to the Underworld to find her magical sapphire--a gift from Persephone's mother, Demeter. While there they are framed for poisoning Hades and barely escape. And, upon their return, they learn that Cassie and Bethany have gone missing--vanished by the new guidance counselor. 
 Sophie, Kai, Theo and Hannah brave the labyrinth to rescue Cassie from her dragon captor (oh, and Bethany, too, if it works out, you know) forcing previous foes to become allies. It's a dangerous mission, and may be the end of all things humanity if they fail. 
 Homerun, Tellulah Darling! 
 This YA paranormal romance is a total hoot. The voice: teen-angst-plus-Greek-god-ennui makes for an acidic, deadpan wit that rides roughshod over all those weepy-weepy-poor-me coming-of-age tales. From the first I was struck with laughter. I was totally endeared to Sophie--all she wants is to be loved for her self without, you know, looking like she wants to be loved at all. Because, for a lot of teens, trying to be anything is trying too hard, and hence, so not cool. The puns are merciless--EX FROM HELL?--take it literally.
