Make sure you read the first book in the series, Memories and New Beginnings(A Spring x Golden fanfic), or this will make no sense and at will do lots of spoiling.
After the death of Trap's long lost lover, Trap goes after the killer. The killer is someone Trap already despises. But, not everything is as it seems.
During Trap's search for the killer, he learns more and more about his past. And the truth hurts like crap. He learns new abilities and overrides his programming more than once, destroying himself in the process. But he won't let it stop him. He won't give up till he finds the killer of his lover.
