The Birthdays tells the unforgettable story of a unique family on the brink of a new generation and examines modern-day marriage, pregnancy, and parenthood. On an island off the coast of Maine, the Miller family reunites to celebrate the father’s seventy-fifth birthday. Each of the adult children is expecting his or her own first child. The eldest, Daniel, grapples with the fact that his wife had to be artificially inseminated. Jake, the middle child, discovers that his wife is carrying twins after many trying years of infertility treatments. Hilary – the free-spirit youngest daughter – arrives in Maine five months pregnant with no identifiable father in sight. Their coming together sets off a series of fireworks, and, after the weekend, none of the Millers will emerge the same.
