Ghost Cave

In Book 1 of the Alice MacDonald Greer Mystery series by award-winning author Helen Currie Foster,
...big-city lawyer Alice MacDonald Greer moves her office to the small town of Coffee Creek, in the heart of Texas Hill Country. She's just beginning to meet the locals when brusque, elderly rancher Ollie West walks into her office. Ollie wants a trust to protect prehistoric rock paintings on his ranch. Intrigued by the unexpected power of the ancient art, Alice obliges.
When Ollie is murdered, Alice feels bound to honor his wishes-despite some family opposition. A series of inept break-ins at Alice's office and ranch escalates into violence by an unknown adversary. Climbing the limestone cliffs of Cloud Ranch to seek inspiration from the rock art, Alice finds herself not only fighting to vindicate Ollie, but fighting for her life.
Ghost Cave plunges the reader into a world of ancient shamans and murderous greed. In the heart of Texas, the passion for land runs deep-sometimes dangerously so.
