Paige Dunn, a character in We Are All Welcome Here by Elizabeth Berg, is quadriplegic.
From the author:
Against the backdrop of the civil rights movement, this novel features a thirteen year old girl living in poverty in Tupelo, Mississippi in the early sixties. Her mother, a single parent, is severely handicapped by the polio she contracted when she was nine months pregnant with her daughter, and she relies heavily on the assistance of an African-American caregiver named Peacie, with whom her daughter has a love-hate relationship.
A lot of issues are looked at in this book, including the notion of what freedom really is, and whether or not it is fair for a child to be intimately involved in caring for a parent so mightily compromised.
