From the creator of My Life As a Teenage Robot comes a middle-grade horror story about a horrible bag, the spine-chilling world hidden within it, and a terrifying adventure into the world of GrahBhag.

Perfect for fans of Coraline, the Spiderwick Chronicles, and Small Spaces.

When Zenith finds a strange, unsettling bag at his front door, he's not sure where it came from or who sent it to him. He knows better than to expect his overprotective older sister Apogee to help him figure it out, because ever since she became a teenager, she's been acting more like a parent to him than a sibling. But he certainly did not expect for a horrifying spiderlike creature to emerge from the bag, kidnap Apogee, and drag her inside to the equally horrifying and unsettling world of GrahBhag.

Zenith sets off into the bag to bring her back but soon finds a bizarre realm where malicious forests, a trio of blood-drinking mouths, and a sentient sawdust-stuffed giant are lurking within the seams. And from every corner of the world come whispers of the Great Wurm, an eldritch horror with a godlike hold over the creatures of GrahBhag, who seems to have a dark, insidious purpose for Apogee. With the help of a greedy, earwax-nibbling gargoyle, Zenith will have to save Apogee from the Great Wurm and help them both escape the horrible bag before it's too late.

With a combination of dry, absurdist humor and no-holds-barred horror, Rob Renzetti has crafted a delightfully imaginative fantasy world that will hook listeners as surely as it will send chills down their spines.
