Realty Check — Piers Anthony

This novel builds bridges between generations as it builds them between worlds. There is a quality here of classic Heinlein. The main characters face the unknown with courage instead of fear. Encountering the fantastic makes them think better instead of not thinking at all. "Reality Check" is a celebration of life, and a love story between grandparents and a granddaughter, between cousins, and between friends. Most of all, "Reality Check" is the first novel to fully explore the impact of the internet on the American family, albeit in science-fiction terms.
