Superpowered Love 4: Losing Better. Superpowered Love, #10

Superpowered Special Agent Gabriel Genêt's first solo mission is simple enough on the surface. He's supposed to visit Hooperstown, North Carolina, find evidence that Andrew Wynne is operating as a vigilante, and then bring him in. It's even simpler given that ten years ago, Gabriel spent a summer alternately torturing and hooking up with Andrew as they tried to ignore their parents' embarrassing affair.
Of course Andrew, the big puppy dog, will be happy to see his old friend and never suspect a thing. Career-driven, cocky young Agent Genêt can hardly believe his luck. But simple rapidly turns into complicated, with Gabriel using Andrew's open arms and attraction to him for all it's worth. Gabriel tells himself he doesn't reciprocate, and then that he can control it, but it's too violent for either of them to deny.
As he gets closer to the evidence he needs, a heady combination of nostalgia, genuine affection, and even understanding brings Andrew closer to him-dangerously close.
