A home run from Orson Scott Card. Duplex features a sympathetic protagonist, a fifteen-year-old brainiac who needs to move his outlook on life beyond his years and become more adult than teenager. Quickly. His family is in shambles, their house is converted into a duplex, and the girl who moves in next door is beautiful and out of his league. Outmatched or not, he falls hard for her and soon discovers that there's much more to her than meets the eye.

Card does a delightful job of dancing along the line between scientific and supernatural,, and the story in engaging and engulfing from page one. Five stars for this one.
