Melanie Honeywell comes from a large family and looks forward to the adoption of a child by her aunt and uncle. But Samantha arrives, not as a tiny infant, but as an obnoxious teen-ager. Worse! Samantha will attend their brand new Christian school and be in the same classes as Melanie. Melanie's best friend Karen Aimee accepts Samantha. Melanie wonders if this is the end of the friendship she's had with Karen since they shared a playpen. Samantha has ruined everything. It seems to be her specialty. She can foul up recipes, mess up Melanie's clothes, and break things, all without even trying. Maybe Aunt Maggie and Uncle Mike will realize that Samantha isn't worth the trouble and send her back.
