Martha is 12 and very different from other kids—no TV, no computer, no cool clothes, and especially no friends. It"s all because of her parents, who are strict members of a religious group called the Brethren. Their rules dominate Martha"s life, and one rule is the most important of all: she must never ever invite anyone home. If she does, their terrible secret—Abomination—could be revealed. But as Martha makes her first real friend in Scott, a new boy at school, she begins to wonder, Is she doing the right thing by helping to keep Abomination a secret? And just how far will her parents go to prevent the truth from being known?
