15 Summers Later by RaeAnne Thayne

Ava Howell seemed to have it all. She moved away from Emerald Creek, Idaho, married the love of her life and published a bestselling memoir. But she never expected that her husband would feel so betrayed by a secret from her past—the truth of what happened to her and her sister all those years ago—that he’d walk away. Now Ava is back home and trying to move on with the only person who can truly understand…

Following years of healing, Madison Howell is finally happy. After college she built a no-kill shelter where she works with animals every day, and she’s in love with the town veterinarian, Dr. Luke Gentry. But she can’t ever bring herself to tell him. Years ago, his dad died protecting Madi and her sister, so how could he ever love her back? 

With the truth laid bare, and the past that Ava and Madison have worked so hard to leave behind threatening everything they have built for themselves, the Howell sisters’ reunion is bittersweet. And as Ava and Madi attempt to remedy the rifts in their lives and reconcile their futures, they must face the demons of their past together.
