Sol’s Savior by May Gordon

Sol Saxon returned home a different man due to his time in the military. He knew he’d be welcomed with open arms by his family, but finding his new normal was proving difficult. However, a personal mission, a last favor to a fallen friend, gave him purpose. Unfortunately, locating Charlotte brought new trouble to his doorstep.
Charlie James works for the mob, and though it isn’t the life she’d always dreamed of, it was the one she had. She’s been tasked with running the underground matches and her focus has never wavered. Then Sol walks in, changing her plans and wreaking havoc on her heart.
While these two are used to fighting, the competition has never been fiercer. Can they work together in order to claim victory or will they both lose more.
