Texas ranger Caitlin Strong is involved in an international plot rooted in secrets from the Cold War in Strong Light of Day, the seventh installment of Jon Land's New York Times bestselling Caitlin Strong series

Afghanistan, 2003: During a mountain raid, a team of Navy SEALs discovers plans for a new and ingenious attack on the United States.

The Present: Fifth-generation Texas Ranger Caitlin Strong is summoned when thirty high school kids from a Houston prep school vanish during a field trip, including the son of her lover, Cort Wesley Masters. As if that wasn't enough, Caitlin also has to deal with a crazed rancher whose entire herd of cattle has been picked clean to the bone.

The link between these two inexplicable events dates back to the contents of that Afghan cave raided by the SEALs, and a plot by forces within Russia to win a war they never stopped fighting. At the center of that plot are billionaire Calum Dane and his multinational conglomerate, currently embroiled in controversy over a genetically engineered pesticide that has the potential to eradicate hunger across the world. Dane doesn't know that this pesticide has spawned a new and deadly enemy capable of destroying the very fabric of American life.

Caitlin's race to save the country weaves through the present and the past, confronting her with the most powerful and dangerous foes she's ever faced. The Cold War hasn't just heated up; it's boiling over under the spill of a strong light only Caitlin can shut off before it's too late.
