Jonah is a fifteen-year-old orphan who thinks he already has enough problems in his life. He's failing all his subjects at school, frequently tormented by the school bully, and can count the people who care about his life (including his cat) on one hand--with fingers to spare. When he faces losing his older brother, he's convinced things couldn't get worse. Then he is awoken in the middle of the night by a clockwork cyborg goblin who robs him of a cherished opal pendant and departs through a magical portal. In his pursuit of the goblin thief, Jonah finds himself cast into a world beneath his own where he must pick his friends wisely, grow up quickly, and choose between an eight-foot evil seductress queen and a thousand-year-old tree nymph if he is to survive --and save the world in the process.
