Sunny Greene is thirty-five, recently divorced, facing the looming prospect of going solo to her little brother’s wedding, and currently trying to find anything plus-sized in the Bergdorf Goodman swimsuit department that doesn’t make her want to cry. It’s not going well. But isn’t rock bottom the perfect place to start a climb?
She decides it’s now or never. Sunny has her PR empire, her gorgeous Chelsea apartment, her two dogs, and her loyal best friends. Maybe it's time to just love her body and accept herself for who she is. With a new commitment to confidence, her journey begins. Who says a plus-sized divorcee can’t put herself first, feel beautiful, and date up a storm?
Of course things are never straightforward in the dating world. Is fate knocking at her door with Dennis, the charming and down-to-earth mailman, or should she be with Ted, the business tycoon who seems ready to make her size-inclusive swimsuit brand a reality? And what should she do about her ex, who shows up unexpectedly, eager to reconnect?
With the same candor and confidence her followers love, Sturino presents her debut novel and brings us Sunny Greene, a Carrie Bradshaw for the next generation. Readers will fall in love with Sunny and root for her journey through the trials and triumphs of dating, friendship, and finding yourself.

Reviews
“Sunny Side Up is the sweet treat you’ve been craving. You’ll fall in love with Sunny — a modern-day Bridget Jones without the toxic self-loathing — as she navigates the pleasures and perils of being a big girl in a big city. If you love Katie Sturino’s Instagram feed and body positive message, you will love this absolute delight of a novel.”
—Jennifer Weiner, New York Times bestselling author of Good in Bed and The Griffin Sisters’ Greatest Hits
"I was team Sunny from page one! Sturino has created a next-gen Sex and the City where furniture store meet cutes are traded for app dating disasters and Carrie’s column is swapped for a Substack newsletter, all set against the backdrop of a new era of NYC hotspots. But at its center—as with the original—is a beating heart of female friendship and an unshakable belief in true love. If you follow Katie on social media, you’ll love how this book is loaded with easter eggs paying homage to the author herself—from Sunny’s pups, to her Max Mara teddy coat, to her Liberty print desk. Full of joy and laugh-out-loud funny moments, this novel was exactly what I needed."
—Becca Freeman, author of The Christmas Orphans Club and co-host of the Bad on Paper podcast
"Funny, poignant, and totally life-affirming, Sunny Side Up will resonate deeply with any woman who has spent her precious time in battle with her own body. I can’t remember when I’ve fallen so deeply in love with a narrator."
—Annabel Monaghan, National bestselling author of Nora Goes Off Script
"Sturino expertly outlines her heroine’s body insecurity and makes a powerful case for feeling beautiful at any size. Readers are sure to be inspired."
—Publishers Weekly
"A novel that offers a character unafraid to embrace who she is: smart, sassy, driven, cheerful—and plus size...Hard work and a belief in yourself will result in success in every endeavor, despite bumps in the road."
—Kirkus
“What gripped me about the novel had…everything to do with Sunny’s determination to create an inclusive luxury swimwear line. In real life, Sturino is a body acceptance advocate. In fiction, she takes us along for a clever and stylish ride, from fabric swatches to boardroom presentation to creation of a logo and beyond.”
—New York Times, The Summer’s Best Beach Reads
“Sunny Greene, the plus-size 35-year-old narrator of [Sturino’s] debut novel, brings her message of positivity to fiction. Recently divorced, Sunny is determined to move into the next phase of her life — which includes juggling several potential relationships — with confidence.”
