“A special book that will make you laugh through your tears with its heartfelt take on happiness and friendship.” —Amy E. Reichert, author of The Optimist’s Guide to Letting Go and The Coincidence of Coconut Cake TWO FRIENDS. ONE HAPPY THING EACH DAY. ONE HUNDRED DAYS. When Annie meets the eccentric Polly, she's skeptical. Polly is her opposite, bright and bubbly—not to mention intrusive—and Annie doesn't have room in her life for a friend like that... until Polly persuades her to join her on a mission: do one thing that makes them happy each day, for one hundred days. As the daily challenge takes off, a real friendship begins to form, and Annie finds herself unexpectedly opening up to the possibilities of life and even new love with the unlikeliest of men. But soon it becomes clear that Polly is about to need her more than ever, and Annie will have to decide once and for all whether letting others in is a risk worth taking.
