Parents need to know that there is some hefty stuff in here. Two teens discuss a man that has poisoned two other men, and who may poison them. Teens are in many perilous situations. A man suggests that two teenagers have sex. A man commmits suicide after leaving another man to die of exposure. There is some language, but is't nothing more than what your average teen already knows. Altogether, it is an adventurous (but confusing) slightly mature book. Okay for 13+.
