3 years, 1 month, 1 week and 6 days since I’d seen daylight. One-fifth of my life. 98,409,602 seconds since the heavy, steel door had fallen shut and sealed us off from the world 

Sherry has lived with her family in a sealed bunker since things went wrong up above. But when they run out of food, Sherry and her dad must venture outside. There they find a world of devastation, desolation...and the Weepers: savage, mutant killers. 

When Sherry's dad is snatched, she joins forces with gorgeous but troubled Joshua - an Avenger, determined to destroy the Weepers. 

But can Sherry keep her family and Joshua safe, when his desire for vengeance threatens them all?
