Anthony. The Survivor Series, #4

Aaron Downing worshiped his mother. She saved his life. She did everything for him. But Anthony Downing has a different perspective. He sees the woman who tossed him into a basement for eight long years and forgot he existed. When Anthony decides he's done being invisible, he packs up and heads for Detroit to stay with his Internet friend Jay, but fate intervenes. Brendan Mears lost everything the day the man with a gun came into his father's store.
Now, he's tethered to a business he can't manage and a brother who resents him. Different in all the ways that matter, Anthony and Brendan struggle to overcome their psychological obstacles, until a crushing betrayal sends them running for cover and each other.
