Shortly after learning they would become the parents of twins, the physician-writer Amit Majmudar and his wife received a devastating in utero diagnosis: one of the twins had a potentially fatal congenital heart defect.

Written in the form of an extended letter, Twin A recounts the epic story of the open-heart surgeries, complications, and prolonged recoveries that Majmudar's son survived in infancy and early childhood. But the narrative turns into something much richer and more expansive than the mere description of a surgical history. Thanks to Majmudar’s ample gifts as a wordsmith, medical and scientific information frequently give way to original poetry and fables, family history, and a series of evocative religious and philosophical reflections about matters of life and death.

The result is a fresh, captivating exploration of the events that transform his son and everyone around him. Drawing strength and beauty from catastrophe, Majmudar’s Twin A creates a moving portrait of a family’s love and a child’s extraordinary resilience.
