Darkest Fear (Myron Bolitar Series #7)

Manhattan sports agent Myron Bolitar is shocked when his former college lover informs him he is the father of her 13-year-old son, who has anemia. But the girlfriend—now inimically divorced from her husband—only uses that fact to convince him to locate the boy's bone-marrow donor, who has disappeared. Bolitar's subsequent quest pits him against a wealthy, publicity-shy, and bitterly scrapping family with hitherto secret connections to a crazed kidnapper. Crisp, focused prose, a wisecracking but gallant hero, and a busy plot make this essential for most collections.
