The Horrible Bag Series : Titles in Order

Book 3
From the creator of My Life as a Teenage Robot comes the epic finale to the middle-grade horror series 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.

They entered the horrible bag… They survived the twisted tower… But can they escape the cursed cloak?

Zenith Maelstrom is running out of time. It’s only been a month on Earth since he was ejected from the macabre world of GrahBhag, with his sister Apogee and best friend Kevin still trapped inside, but in GrahBhag, years are passing. And with the horrible bag out of reach, Zenith has no way to get back to save them.

That is until a ragged portal opens up in an alley’s brick wall, spewing out torrents of water and a tentacled monster, and allows him passage back into GrahBhag. Once there, he learns that things are more dire than he thought, as the literal fabric of the terrifying world has begun to rip at the seams. If Zenith has any chance to save his sister—and maybe even GrahBhag in the process—he’ll have to dive deeper into the secrets of this terrible world than he ever has before. For the Wraith is haunting, and time is not on his side…

With a combination of dry, absurdist humor and no-holds-barred horror, Rob Renzetti has crafted a delightfully imaginative fantasy world that will hook readers as surely as it will send chills down their spines.
Book 2
From the creator of My Life As a Teenage Robot comes the second story in a middle-grade horror series 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.

Zenith Maelstrom knows he’s forgetting something…

But he can’t quite remember what. He wakes up to notes in his handwriting with messages like, “Prepare for battle!” – but what battle? – and his sister Apogee seems to grow angrier with him by the day. It’s not until he finds Apogee sneaking back into the horrible bag hidden away in their basement that all the dreadful details about GrahBhag resurface. The spiderlike Shlurps. The trio of foul mouths that hunger for blood. Eldritch horrors around every corner.

Desperate to save Apogee from her ill-planned attempt to right the wrongs of their last trip into the bag, Zenith is forced to follow her into the bizarre world that has certainly not forgotten them. Between old foes set on vengeance like Raggedy Albert and terrifying new ones like the haunting Wraith, Zenith will have to put things right with his sister without falling into the clutches of those who would do him harm. For if he is caught, Eternity Tower awaits…

With a combination of dry, absurdist humor and no-holds-barred horror, Rob Renzetti has crafted a delightfully imaginative fantasy world that will hook readers as surely as it will send chills down their spines.
Book 1
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 readers as surely as it will send chills down their spines.
