Among the 11 spooky places featured in this book, readers will explore a cave of lost treasure hidden by Spanish conquistadors over 350 years ago; a cavern where a 13-year-old boy discovered the largest underground lake in the United States; and a cave where the mournful ghost of a young woman searches desperately for her lost love. The mysteries of these eerie places and the spirits said to still haunt them will keep readers turning the pages.
