Tuesday Night at the Blue Moon, Debbie Fuller Thomas

I think this is the last book from last year's ALA swag pile. A nice story about kids who were switched at birth which is only discovered when one is diagnosed at about 12 with a genetic disease that doesn't run the family she has lived with. When one family sues, the other girl is ordered by the courts to move in with her biological family. That's where the book starts. A little preachy, but heartwarming, if you can believe that.
