Explore haunted caverns in a mystery series filled with hidden treasure, ghosts from the wild west, and a sweet friendship that could become something more.

Ever since she was a young child, eighteen-year-old Winter has been best friends with the ghost who resides in her family's caverns. No one else could see him. They wrote him off as Winter's "imaginary friend." But now that dangerous incidents are occurring near Lago Caverns, he may become Winter's secret weapon in getting to the bottom of the mysteries.

When a teacher goes missing amidst ghastly rumors, Winter is the only person who believes something nefarious is at play...especially when the teacher's absence spells trouble for Lago Caverns. Armed with her friendly ghost, her own fearlessness, and her ability to craft stories that leave listeners spellbound, Winter will get to the bottom of this mystery—and others—to save her home.

This collection includes Hollow Wishes, Dark Refrains, and Wicked Regrets—the complete Winter's Cavern trilogy.
