The Haunting of Old Splinter

Innocent wishes turn decidedly sinister in this chilling horror for fans of Katherine Arden and R. L. Stine. Peter and his half brother, Adrian, live in the shadow of Old Splinter-a formerly lavish estate now in ruins. Rumored to have once housed an eccentric magician, it's now home to little more than spiderwebs and mold. Tasked with renovating the crumbling mansion on behalf of their wealthy uncle, Peter's stepdad is at his wits' end.
And the cracks are beginning to show in their once-happy cottage. A mysterious local legend may be their only hope. The wishing claw, a magical hand that grants your deepest desires, has spell-bound townsfolk for centuries. If it's real-if he can find it-then Peter might just save his family! But wishes are tricky things and they always come with a price. What starts innocently enough soon unearths much more than Peter bargained for, including a dark secret lurking in the walls of the mansion.and a monstrous hunger that comes knocking at his door.
