My Beach Essentials: Jessica Knoll

The novelist on her go-to sunscreen and her current read

Whether she’s writing all day at a poolside picnic table or on the road promoting her new book, the best-selling author behind The Favorite Sister knows how to get the most out of summer. “My ideal day involves a run or long walk on the beach and a dunk in the ocean in my sports bra, followed by a cold brew from Jack's Stir Brew Coffee,” she says.

Here, Knoll shares her favorite warm-weather must-haves.
