ROCK HEAVEN is the first novel of the Doormaker series, which is a "otherworld" fantasy where a young teenager is transported to different worlds. In this case, Maella and her family are "doormakers." They are cursed by their gift, unable to open any door they encounter without creating a dimensional portal. It doesn't matter whether it's a cabinet, drawer, or screen door--any door they open will expose them to extraterrestrial threats. They live impoverished, paranoid lives where they are hated and shunned as outcasts. Then Maella breaks the one rule her family has established, "never open a door."
