The Farm From Anywhere by M.R. Alger

Thirteen-year old Phillip Montgomery didn't want to spend summer vacation with his cousins in the rural Midwestern town of King's Hill. But discovering the Farm From Anywhere is beyond anything Phillip, and his new friend Dan, could have imagined. It's supernatural, it's mysteriously magical, and it's dangerous. Something threatens the Farm, and what follows Phillip and Dan outside could be just as deadly as what is inside.
