Weeks of sun and fun take an unexpectedly deadly turn

When her long-term boyfriend books a six-month jaunt through Asia without telling her, London native Rowena feels abandoned. Then a chance encounter at a New York wedding she’s flown in to photograph lands her a much-coveted summer time-share in the Hamptons. She figures it will be a nice change of scenery — or at least a way to while away the months. Instead, she ends up with booming work opportunities, wacky roommates and an instant, if slightly troubling, connection to a handsome stranger. Throw in socialite hijinks and a high-stakes mystery, and suddenly Ro’s summer abroad turns out to be life-changing. An enjoyable, beach-perfect romp with a relatable and endearing heroine.

The Summer Without You, Karen Swan, $20.
