The Beast of Skull Rock
(Monsterious #4)

Twins Simon and Jade are thrilled to spend the summer with their grandfather in the beachfront resort town of Skull Rock. They're especially looking forward to helping out at his spooky cabinet of curiosities museum, full of creepy old relics, taxidermy specimens, and sinister displays.

But lately there have been disturbing reports of store break-ins and sightings of a frightening creature in the area, scaring away the town's much-needed tourists. When the twins hear eerie noises coming from the museum after hours and see strange scratch marks on the door, they decide to investigate. As the creature attacks mount, Jade and Simon begin to suspect the impossible: Could one of their grandfather's museum monstrosities be coming to life each night to prowl the boardwalks of Skull Rock?
