The Talisman - Stephen King & Peter Straub

Twelve-year-old Jack spends his days alone in a deserted coastal town, his father gone, his mother dying. Then he meets a stranger - and embarks on a terrifying journey.

For Jack must find the Talisman, the only thing that can save his mother. His quest takes him into the menacing Territories, a parallel world where violence, surprise and the titanic struggle between good and evil reach across a mythic landscape.
