Unfortunates by Lillian Graves

Seventeen-year-old Vanessa is about to get a new life—whether she wants one or not. With a best friend keeping a crazy big secret from her and her parents rubbing their perfect high school love story in her rocky relationship's face, she doesn't have any more cares to give. So when Adam, a ghost who calls himself an Unfortunate, tells her she is his Match - the one who can help him earn his second chance at life by committing random acts of kindness – she nearly blows a fuse. 

No, scratch that. It shot straight off. I mean, why help a ghost who may just be in her head? What was in it for her?

After the denial and resistance pass, Vanessa begins to realize not all of arrangement is against her favor. There is something rather cute about Adam and maybe, just maybe, if he is telling the truth and she brings him back to life, he could be her new date to prom.

But can her selfish ways live up to his expectations?
