When Nick and Allie are killed in a car accident, they find themselves in Everlost, a limbo for kids somewhere between life and “the light at the end of the tunnel.”  Nick is content to stay in Everlost with Mary Hightower, who looks after the children of Everlost, while Allie searches for a way to see her family.  As they battle terrifying creatures and try to keep from sinking to the center of the earth, they learn that there are some fates that are more frightening than death. (Lori Loranger, Librarian, Grisham M.S., Round Rock ISD, TX)

Booktalk #2

Nick and Allie are killed in a car crash and on their way to the light they bump into each other, knocking themselves off the path and into another sort of afterlife. They find a world inhabited by the "souls" of children who didn't make it down the tunnel. This world, which parallels that of the living, is filled with danger and the opportunity for adventure.

Shusterman presents an intriguing world for the afterlights (those who don't make it into the light) and uses this fun playground to write a rip-roaring adventure story.
