That Summer by Jennifer Weiner

From the #1 New York Times bestselling author of Big Summer comes another deliciously twisty novel of intrigue, secrets, and the transformative power of female friendship. Daisy Shoemaker can’t sleep. With a thriving cooking business, full schedule of volunteer work, and a beautiful home in the Philadelphia suburbs, she should be content. But her teenage daughter can be a handful, her husband can be distant, her work can feel trivial, and she has lots of acquaintances, but no real friends. Still, Daisy knows she’s got it good. So why is she up all night? From the manicured Main Line of Philadelphia to the wild landscape of the Outer Cape, written with Jennifer Weiner’s signature wit and sharp observations, That Summer is a story about surviving our pasts, confronting our futures, and the sustaining bonds of friendship.
