Book excerpt: From the bestselling author of One Child comes the story of three of former special education teacher Torey Hayden’s most extraordinary challenges. Nine-year-old Cassandra, kidnapped by her father and found starving, dirty, and picking through garbage cans—is a child prone to long silences and erratic, violent behavior. Charming, charismatic four-year-old Drake will speak only in private to his mother—while his tough, unbending grandfather's demands for an immediate cure threatens to cause irreparable harm. And though she had never worked with adults, Hayden agrees to help fearful and silent eighty-two-year-old massive stroke victim Gerda—discovering in the process that a treatment's successes could prove nearly as heartbreaking as its limitations.
