Originally published in hardcover last year, the paperback release of this fun Summer mystery is perfect for beach reading while ruminating on how water ices can save the world. Half-sisters Josie and Stella spend every summer together: Josie lives in Australia with her mom, while Stella lives in New York with her mom and stepdad. They share their summers – and their dad – together at the Jersey Shore, where they have their rituals. This year, Stella is pushing back against those rituals, because she’s on the verge of high school and wants to act more adult; Josie revels in their childhood memories. What starts out as a story where two sisters are growing up yet afraid of growing apart gets infinitely more interesting when you realize that chapters alternate between the sisters’ story and a debriefing at a police station. Something big has happened, as the story unfolds through each chapter, and it has to do, somehow, with the new smoothie store that took the place of Josie’s beloved water ice shop; a pop star coming to perform a concert at the pier, and the jellyfish population, currently undergoing a marine life crisis. This family story becomes a co-plot to an environmental mystery that brings the sisters back together to solve as they work out their growing pains, and it is guaranteed to keep readers glued to the pages. There’s a fun cast of supporting characters, great pacing and dialogue, and an eloquent statement about the environment and how we affect it, for better or for worse. Put this on your shelves with other summer books like Kayla Miller’s graphic novel, Camp, Mae Respicio’s Any Day With You, Melissa Savage’s Lemons, and – naturally! – Rita Williams-Garcia’s One Crazy Summer.
