Love Will Keep Us Together (Miracle Girls)

Riley McGee has the whole world open before her. She could get into any college, major in any subject, become whoever she wants to be. . . . But the truth is, Riley has no earthly idea what to do. She's paralyzed by indecision, afraid of the changes she faces, and as graduation day inches closer, it feels more and more like a threat.
  Meanwhile, her autistic brother, Michael, is struggling to fit in at Marina Vista and stay on top of his classes. Riley tries to keep an eye out for him, but when Ms. Moore suggests pulling Michael out of school, Riley has to fight for her brother--and against her favorite teacher. And things take another turn when her ex-boyfriend, Tom, arrives, hoping to give their relationship one more try. On top of that, an ambitious new pastor makes her question everything she thought she knew about faith.
