The Summer Escape: A Novel - Jill Shalvis

Secrets are revealed and forbidden sparks ignited in this sizzling Sunrise Cove standalone, a tale of enemies to lovers, redemption, missing treasures, and love—by romance superstar and New York Times bestselling author Jill Shalvis.
Anna Moore didn't just wake up one day and decide to go on a wild quest—especially since her life no longer lends itself to wild anything—so how in the world does she end up racing against the clock with Owen Harris, a sexy, enigmatic adventurist, to prove her beloved dad innocent of stealing a million-dollar necklace?
It's all Wendy's fault. Her older, bossy sister, who's seven months pregnant and on bed rest in their small Lake Tahoe hometown, is desperate to clear their departed dad's name. Owen, though, is convinced he's guilty as hell and wants to return the jewelry back to its rightful owner—his elderly great aunt. Together Anna and Owen go on a scavenger hunt for clues to the past (with Wendy remotely along for the ride via an earbud, supplying a running wry commentary to boot).
On opposing sides and suspicious of each other as they are, Anna and Owen still can't deny the inexplicable and explosive chemistry between them on this heart-stopping adventure, the outcome of which will prove the necklace isn't the only thing stolen—their hearts have been as well.
