Legends collide with reality when a boy is swept into the magical, dangerous world of a girl filled with poison.
Everyone knows the legends about the cursed girl—Isabel, the one the señoras whisper about. They say she has green skin and grass for hair, and she feeds on the poisonous plants that fill her family’s lush Caribbean island garden. Some say she can grant wishes; some say her touch can kill. Seventeen-year-old Lucas spends summers with his hotel-developer father in Puerto Rico, and he’s grown up hearing the stories. When letters from the cursed girl mysteriously appear in his room the same day his girlfriend disappears, Lucas turns to Isabel for answers—and finds himself lured into her strange and enchanted world. But the more entangled Lucas becomes with Isabel, the less certain he is of escaping with his own life.
