The Monsters of Spiders' Rest — Jane Tesh

Life isn't easy for a spider, especially for Flickfoot, an intelligent spider created by Dr. Vil, a mad scientist who has died, leaving him to fend for himself in Spiders' Rest with his two companions, Plinks and Jellyroll. The spiders are not alone, with other creations, including a hoard of monsters living in the woods around the Andrean city of Specter, monsters kept at bay during New Season by the Specter Exterminating Service, including Holly Dark, a young agent determined to destroy all monsters, even spiders.

When the doctor's grandson, Tylin, decides to move in, Flickfoot realizes he may have an ally, if he can convince Ty that the spiders are harmless. But as horrifying and threatening as Dr. Vil's monsters are, Flickfoot discovers far worse creatures plot to take over Specter. He needs Ty's help, even though Ty has connections to the mysterious Star Cult and a secret that could ruin everything.
