Anna Dressed in Blood

Teens known to the main character, Cas, die gruesomely -- three of them in the present, one in a flashback that includes fear of sexual abuse. Two of these teens are found dead, ripped apart with blood everywhere; one is killed by a parent; one is ripped in half by a ghost. The family cat is killed. People unknown to Cas are found killed and partially eaten. Cas' father had also been found dead, partially eaten, 10 years before. Hauntings show gory details of deaths, such as spilled intestines. Cas dispatches other ghosts with a special knife and learns their stories of how they died, usually violently. He suffers many injuries including a concussion, near organ failure, and bruises.

A few kisses with talk of teens making out.

Regular and varied swearing including various forms of "f--k" and "s--t."

Teen drinking to drunkenness at a party. There is a designated driver, however. Some teen smoking.
