One morning Taylor Harris's twenty-two-month-old wakes up listless and unresponsive. She rushes him to the doctor, where her maternal instincts are confirmed: something is wrong. With every question the doctors answer about Tophs's increasingly troubling symptoms, more arise, and Taylor dives into the search for a diagnosis. When Taylor brings Tophs to a geneticist, she hopes that this time, she'll leave with answers. The test reveals nothing about what's causing Tophs's drops in blood sugar, his processing delays - but it does reveal something unexpected about Taylor's own health. What if her son's challenges have saved her life? And how can she choose the best path forward?
