A ghost story kids can join – if they dare!

Being the new kid in town is never easy, and 13-year-old Jack Davids is trying hard to adapt to his new, seemingly sleepy hometown of Newbury. Before long, Newbury’s Hidden Side – a bone-chilling, long-forgotten realm filled with ghosts – threatens to take over the town. With his new best friend Parker and the brilliant scientist J.B., he’ll use a new interactive app to embark on the ghost-catching ride of his life!
