The Memory Keeper's Daughter

"On a winter night in 1964, Dr. David Henry is forced by a blizzard to deliver his own twins. His son, born first, is perfectly healthy, but the doctor immediately recognises that his daughter has Down's syndrome. For motives he tells himself are good, he makes a split-second decision that will haunt all of their lives forever. He asks his nurse, Caroline, to take the baby away to an institution. Instead, she disappears into another city to raise the child as her own." - back cover.
