CREEPY CASE FILES MARGO MALOO HC GN (2025)

"Now that Charles has helped Margo Maloo close a case, he thinks he's an expert on things that go bump in the night. But Margo knows he still has a lot to learn about Echo City's hidden monster society-he doesn't even know the difference between a poltergeist and a wraith! So as long as he doesn't get in the way, she lets him tag along on her adventures. As Margo's assistant, Charles meets a variety of monsters, from imps to vampires. And lately they all say the same thing: living secretly in Echo City is getting harder. Humans and their smartphones are encroaching on monster territory, eager to photograph paranormal activity and share it with the world. Some monsters are tired of hiding and ready to fight. Can Margo and Charles prevent all-out war between human and monsterkind?"

As the assistant to Margo Maloo, Charles has gone on assignment in some pretty interesting locations. He's been to a vampire's lair, an ogre's den, and even a monster grocery store! But he's never been to Downside, Echo City's underground monster metropolis that is super mysterious and definitely off limits to kids. But a settlement of giant spiders is about to be dynamited by unwitting construction workers - and, coincidentally, one of those giant spiders "accidentally" bit Charles. His cure and the spiders' salvation lie in the Downside - if Charles and Margo can make it in time.
