After years in the army, Oliver Hayes, a cold-hearted and broken veteran, returns home carrying the scars of war, not just on his body but far within his very soul. Tormented by memories he can't forget, he isolates himself from civilization, believing that all hope is gone. Enter Ava Hagen, a lively and spirited barista at the local café. Ava had been through her own share of challenges, but she was determined to live her life to the fullest. When Oliver starts to visit the café by routine, she notices the pain and hurt in his eyes. Intrigued and curious, she slowly begins to dismantle the walls he had constructed around himself. In Mending Hearts, two broken hearts find comfort in each other, learning how to heal and love.
