Welcome Home, Jellybean — Marlene Fanta Shyer

Gerri pushed the EMERGENCY button on the elevator. When the siren went off she began to jump and scream. ...If this was a sample of what life with my sister was going to be like, we were probably making a monster mistake....

Neil Oxley doesn't really know his older sister at all, and neither do his parents -- because the only place that Gerri has ever lived is an institution. Gerri is retarded. But now their mother thinks that she is ready to come home.

None of them truly understands what it will be like, but there is one thing that they do realize: living with Gerri will change their lives forever.
