Isabelle is fascinated by wind. And this year, she's determined to win the middle school science fair with her wind machine. She's just as determined to have her brother, Julian, who has a severe form of epilepsy and uses a wheelchair, serve as her assistant. But after Julian has a grand seizure, everything changes. Isabelle is suddenly granted entry into Las Brisas, a magical world where Julian's physical limitations disappear, and one, she discovers, that he visits every night. The more Isabelle explores Las Brisas, the more possibilities she sees--for Julian, and for herself--and the more she finds herself at odds with her parents.
