Boss of the Underworld (Hardcover) (ISBN-13: 9781250430380)

The first book in a new hilarious middle grade graphic novel trilogy about a girl who falls down a manhole and has to save the Underworld from an evil green menace, perfect for fans of InvestiGators and Ham Helsing.

Shirley didn't mean to fall down the manhole. Actually, she didn't fall . . . Something dragged her down into the abyss. But now, before she could even collect her thoughts, she is forced to save an entire subterranean society of misfits from the evil clutches of a big baddie known as "The Boss."

Shirley and her new giant cockroach friend George must triumph over scary foes, resist eating delicious things in the sketchy forest, navigate the Bog of Intense Emotions, and find their way through the dark maze of the sewers.

And little does Shirley know that she has a history with the Boss of the Underworld. Will Shirley and George be able to conquer this quest, or will they be left swimming with the fishes?
