A woman went missing years ago. The official report says she was a victim of Deadman's Falls, but her family isn't so sure. Ellie recently returned from an enlightening trip to Argentina with a lot on her mind. And a huge decision ahead of her. When new evidence is revealed in the missing woman's case, Ellie is asked to help. It was supposed to be a simple trip into the state park. She and Xander would hike in, see where the trail led, and hike back out. They didn't expect the storm to hit. Now, they're trapped in a cave with an unexpected guest. Will Ellie be able to solve the case? Find out in Spelunking Speculation-the fifth book in the Magical Mane Mystery series.
