Slumberland (Unabridged‪)‬

From the author of Brightside.

Sierra Preston is a ray of sunshine whose life is almost as perfect as the weather she predicts.

She has the best of friends, the most loving family, and lives each day without a cloud in the sky.

It’s not until she’s struck with a new ability to solve complex math equations, that she’s able to understand the reality of the world around her. But her newfound gift comes at a price.

When insomnia leads her to the darkest corners of insanity, Sierra learns a devastating truth: You don’t need sleep to live a nightmare.
