Allison Albrecht and Samantha Cannizarro are thrown together when their parents become engaged. Sam is deaf, so Allison begins to learn sign language. Allison is eager to please Sam and to make a good impression on her. Sam does not care about good impressions. She is a loner, always has been. She resents her new instant family, especially her stepmother-to-be. Sam is also reluctant to bond with three-year-old Allen. However, Allison and Allen gradually crack Sam's facade, and the two girls fall in love.

But life in a stepfamily is rarely easy. Throw in romance between two stepsiblings, and the ride is going to be bumpy.
