Dynamic Optics: A Del Sanderson Adventure (Hardcover) (ISBN-13: 9781960059420)

Del Sanderson wishes for a quiet life in Bozeman, Montana-library visits, dark-roast coffee, and an occasional blueberry scone.

When he finds a cryptic note attached to a hundred-dollar bill, his quiet life takes a sharp turn. The coded message, addressed to someone named Michelle, leads Del into a shadowy world where nothing is coincidence, and danger lurks behind ordinary routines. Del observes two new passengers on the regular bus he often takes to the library. The two silent men who always seem to be watching meet with a mysterious woman, graceful and guarded, who may be the "Michelle" the note was meant for. As Del digs deeper, he finds himself under the scrutiny of strangers who know more about him than they should. His instincts-honed long ago through secrets he keeps hidden-tell him this is no coincidence. The note is a warning. The stakes are far greater than he can yet imagine.

Del relies on old friends in the FBI and new friends in the DEA, along with his highly trained math skills, to help him unravel his puzzle. Along the way, he discovers a spark of romance he never expected-an affection that tempts him to risk not only his safety but his heart. Del's adventures continue. He is driven to complete them.

Dynamic Optics is fast-paced, layered with suspense and filled with sharp twists. It is a gripping thriller in which everyday moments unfold quickly. Del continues to choose which rules he will follow.
