Chains by Kelli Maine

I absolutely loved this story. From the first page I was sucked in. This foster kids were each others strength. Essentially told from the POV of Tyler a would be MMA fighter finds the girl he left behind. As kids Tyler, Alex, and Danny were adopted by an abusive man who hid who he was to the outside world. Even though were no longer underage he still haunted them and for Danny he could never quite let her go. Somehow the three find each other again. Taking joy in being together and the few moments of fun they had as children. When it seems like the trio would all find their happy ever after tragedy strikes. A ending that made me hold my breath. Beautifully written heartbreaking story.
