Everlost by Shusterman

This story takes place in a site between life and afterlife. In this place some foods like lovingly made birthday cakes, transportation like the Hindenburg, buildings like the twin towers, land where disasters have occurred and so on exist and kids ages 15 and younger can exist there, have adventures there, get stuck forever in a rut there. A few older kids have discovered how to reign, have power over others there, as long as they don't share the secret of going into the light...Nick and Allie discover the lies of Mary who seems sweet but isn't, the very scary Haunter with powers he will share for a price and the much feared McGill who they barely manage to escape after many adventures. Not my favorite Shusterman book but not a bad scary adventure story. Jdw 10/24/07
