A zombie, a ghost, a vampire, and a witch make up one unique group of monster friends who don't exactly fit in with the other monsters. While their friends and family are busy scaring humans and doing general scary stuff, these four monster friends are using their skills for the greater good. As a result, they often find themselves in funny, unexpected situations. It's not easy to be different, but these monsters prove it's important to be yourself. The Monster Heroes early chapter book series finds these friends tackling one adventure after another.
