Showing Everlost by Neal Shusterman

Not every child who dies goes on to the afterlife. Some are caught halfway between life and death, in a sort of limbo known as Everlost: a shadow of the living world, filled with all the things and places that no longer exist. It’s a magical, yet dangerous place where bands of lost kids run wild and anyone who stands in the same place too long sinks to the center of the Earth.

Allie and Nick don't survive the car crash, and end up in Everlost, where coins are more valuable than anyone knows, fortune cookies tell the truth, monsters are real, and the queen of lost souls lives in a once-beloved tower. Nick and Allie have to learn to survive in a world with different rules, and figure out who they can trust--and who they must oppose at all costs. At stake is nothing less than the fate of Everlost and the living world they have left behind.

In this gripping trilogy, Neal Shusterman explores questions of life, death, and what just might lie in between.
