INGRID’S FAVORITE

William Morrow, $25.95 (signed first edition)

A mysterious disease washes ashore and threatens to extinguish all of humankind, and crack special-op science team SIGMA is on the case. While some members converge on a cruise ship converted into a hospital, team leader Gray Pierce tangles with a lady assassin. She defects from her shadowy organization, The Guild, and joins the fight to defeat the terrorists who are determined to weaponize the disease. As time runs out for humanity, the key to survival may lie in solving the mystery of the armada that vanished while under the command of famous explorer Marco Polo. This is the third in Rollins' Sigma Force series. Rollins combines some great scary-but-true science lore, great action scenes, and crackling dialogue.
