Book 2 in the Dr. Abby Wilmore Series

Where Light Comes and Goes brings back Dr. Abby Wilmore, the young family physician who was the protagonist of Miller's first novel, The Color of Rock. Abby has accepted the directorship of a summer clinic in Yellowstone National Park where she hopes to expand her medical skills. She arrives to find herself working above the increasingly restless Yellowstone supervolcano, treating visitors, staff, and locals, all while evading the advances of a lecherous concession manager and maintaining a long-distance relationship with her partner who stays at the Grand Canyon Clinic. As tremors in the park escalate and the lakes seethe with bubbling gases, Abby learns that some-one is mysteriously killing the bison.

What follows is an engrossing mystery unfolding in a spectacular setting with rich, quirky, and endearing characters and unexpected plot turns. While an overworked Abby makes new friends among her clinic staff and patients, tension builds as the volcano seems to be moving closer to a major eruption and the bison killings become more frequent. Soon, Abby finds herself in mortal danger as the story races to a thrilling and unexpected conclusion.

Sandra Cavallo Miller demonstrated in The Color of Rock that she is a gifted storyteller. Where Light Comes and Goes deftly combines a gripping mystery set in the accurately depicted routine of a busy medical practice amid the wonders of Yellowstone's magnificent scenery and wildlife. This is entertaining reading at its best.
