Margaret, Max, and Edie Bramble are adult siblings careening through wildly different lives. Margaret, mother of three, drowning in a sea of runny noses and lost mittens, a witty woman at wits end, is now adding her ailing father into her already-chaotic life. Edie is young, single, clicking smartly down city streets in good shoes, but struggling mightily to anchor her intensely solitary life. Max, a new father, is buckling under the weight of added responsibilities. Over the course of one critical season, a long hidden secret will be revealed, changing all they thought they knew about one another and about themselves.
