Tink Elledge is back in the saddle-and in more danger than ever. The race is a hundred miles through the Sierra Nevada against a backdrop of Darwin, evolution, and intelligent design. Smart, deftly plotted, and tuned to ongoing debate, this mystery is perfect for fans of Dick Francis. Tink Elledge is a woman who doesn''t take well to sitting still-not when it comes to husbands, not when it comes to looking after her stepson Stephen, and certainly not when it comes to horses. So when she gets the chance to ride in a competition again-even on a trail as grueling as the steep twists and turns of the legendary Tevis endurance trail ride-she jumps at it. In the Sierra mountain wilderness, she and her friend Isabel-an avid horsewoman and Darwin devotee--will race across one hundred miles of spectacular gorges and cross heart-stopping fords.? Meanwhile, Stephen and Tink''s husband, Charlie, are nearby working on a new partnership with the brilliant but secretive scientist James Grant-Worthington. When Grant-Worthington suddenly dies of not-so-natural causes, the entire deal is thrown into question. Eager to help, Tink begins searching for clues, starting with Josh Untemeyer, the PR manager for the institute Grant-Worthington founded to promote the theory of intelligent design, who has also been pursuing Isabel. As Tink and Isabel join the pack of elite riders and their horses scramble up the vertiginous, narrow trail, Josh goes missing. Tink must sort through the secrets and lies in a race against time to cross the finish line and save the two people she cares for most in this lively, page-turning novel from acclaimed author Holly Menino.
