Just One Wish book by Janette Rallison

Seventeen-year-old Annika Truman knows about the power of positive thinking. With a little brother who has cancer, it's all she ever hears about. And in order to help Jeremy, she will go to the ends of the earth (or at least as far as Hollywood) to help him believe he can survive his upcoming surgery.

But Annika's plan to convince Jeremy that a magic genie will grant him any wish throws her a curveball when he unexpectedly wishes that his television idol would visit him. Annika suddenly finds herself in the desperate predicament of getting access to a hunky star actor and convincing him to come home with her. Piece of cake, right?

Janette Rallison's proven talent for laugh-out-loud humor, teen romance, and deep-hearted storytelling shines in a novel that will have readers laughing and crying at the same time.
