The Ghost Miner's Treasure (Haunted series)

Jon and Tania are traveling with the ghost hunter TV show again, this time to the Superstition Mountains of Arizona, where the ghost of an old miner is still looking for his lost mine. The siblings want to help him move on—but to help him resolve the problem keeping him here, they’ll have to find the mine. And even then, the old ghost may be having too much fun to leave! It’s a good thing Tania can see and talk to him, because the kids will need his help to survive the rigors of a mule train through the desert, a flash flood, and a suspicious treasure hunter who wants the gold mine for himself.
