Amulet: Book 1. The Stonekeeper
After a family tragedy, Emily, Navin, and their mother move to an old ancestral home to start a new life. On the family’s very first night in the mysterious house, a strange noise lures them into the basement, where Em and Navin’s mom is kidnapped by a humongous, tentacled creature and dragged down behind the basement door.
The kids give chase down a twisty spiral stairway and find themselves in a strange and magical world below. Most surprising of all, it seems that their great-grandfather, who was an inventor and puzzle maker, was there before them—and he’s left some unfinished business.
Now it’s up to Em and Navin to figure out how to set things right and save their mother’s life!
