A legendary treasure, a vanished professor, and a haunted library - welcome to the world of Emily Plankhurst. In the quaint town of Taos, New Mexico, Emily has inherited her family's research library and is determined to continue their legacy. But when a renowned history professor goes missing while searching for a long-lost Conquistador treasure, Emily finds herself caught up in a twisty mystery.

With the help of her ghostly grandmother and a worried colleague of the professor, Emily must navigate through a town full of treasure hunters and clues to find the truth. But as she delves deeper, all Emily knows is that the missing professor had checked out a couple of rare documents from her library, and one of them just might be the authentic map to the treasure!

Will Emily be able to locate the professor before someone else gets hold of the map? And will she learn whether the famous Conquistador gold actually exists? Find out in this first book in a new spinoff series from USA Today bestselling author Connie Shelton.

For fans of Shelton's earlier Samantha Sweet series, The Ghost in the Library Series is a must-read. With a strong and determined female lead, a charming small town setting, and a thrilling plot full of twists and turns, this book will keep readers on the edge of their seats.
