An otherwise intriguing twist on the paranormal is let down by forced melodrama and inexplicable secrets. Goth girl Eden—ignored by her mother, forgotten by her friends— is contemplating suicide when she meets the boy of her dreams. Luscious Az makes life worth living, and Eden spends an idyllic summer with Az and his gay best friend, Gabriel. Unbeknownst to Eden, Az is an angel, or at least used to be one. Now he's half-Fallen, caught between heaven and hell, holding onto Upstairs through painful effort and the assistance of the still-holy Gabriel. Az’s enemy, Luke (three guesses as to his true identity), wants to drag Az fully into the ranks of the Fallen, and he will surely torture Eden if he finds her. But Eden's no ordinary girl. After an apparent tragedy breaks her spirit, Eden becomes a Sider, an undead suicide non-survivor, wandering the boroughs of New York in Goth finery. She makes both friends and enemies among the Siders (although the motivation of both is thoroughly unclear) and gains notoriety as a sort of afterlife Jack Kevorkian, helping failed teen suicides to a more successful death. Eden struggles to survive with the help of her potty-mouthed celestial posse. Those enamored enough of troubled-but-cute heroes won't mind the chaotic prose, plot holes and unlikable side characters—and will be thrilled by the setup for volume two. (Fantasy. YA)
