A Season of Perfect Happiness fundamentally questions what makes a "good" mother, with a propulsive and heartrending portrayal of one woman's efforts to find her voice. Ten years after an unspeakable tragedy caused Claire to flee her hometown in Delaware, she finally feels content. She has a quiet, tidy life in Wisconsin, a place she picked at random for its shape on a map. Her careful existence centers on a simple keep her social circle small and keep the past a secret. But when she meets Erik - a lighthearted theater nerd who gives Claire more of a chance than she's given herself in a long time - that plan seems increasingly impossible, especially after she finds herself emotionally entangled not only with Erik, but with his ex-wife, Annabelle; their three young children; and a small set of friends, the kind she'd always wanted to have around her. Life after the accident can be full of joy, Claire realizes - going on a date to see a thousand-pound pig at the state fair, giggling over obscure inside jokes with friends at a music gig, making smoothies while the kids wear their infamous cooking hats. Being a partner, a best friend, a mother. But when a person from her past arrives, Claire's worst mistake threatens her new life, and the deep friendships she's made hang in the balance. If Claire chooses to share the parts of herself she has kept locked away for so long, will the family she has built still recognize her - and have a place for her? Or will everything she has spent the last decade working toward fall apart?
