The Haunted Stables by Eli B. Toresen
The Pony Club
Lisa took a step into one of the stalls but stopped short. What was this? She felt as if someone had put a big hand around her neck and squeezed it. All of a sudden it was difficult to breathe, and she felt a cold sweat break out on her back and forehead.
Evil! The word popped into her brain out of nowhere. This place is filled with evil. The next minute the strange sensation was gone, but she noticed her arms were covered in goosebumps, even though she was not feeling cold. Am I getting sick? She thought worriedly.
Lisa and Karen are helping Marc clean out the old stables he has inherited. Finding an old jar with a strange inscription sets off a chain of scary events. Someone... or something... is after Marc and his family, but why? Will Lisa and Karen be able to solve the mystery before it's too late?
