Satan!: Hell High, Book 2
Whoever thought having a succubus for a girlfriend would turn your life upside down? Now Sherman is on his way to meet Satan. Fortunately, he's not quite the bad guy everyone has made him out to be. Less fortunately, The Lord of Evil has a job for Sherman, and let's just say that if our impromptu hero fails, well, he'll have 99 problems but a succubus won't be one.
