Raphael by Serena Simpson

Raphael was a genetically engineered assassin which would have been great if the people who created him hadn’t screwed up. Unlike those around him, he knew his days were numbered.
Effie was living low-key, pretending to be like everyone walking the streets.
A chance meeting on a dance floor brought two people together that should have never met. They both chose to stay apart for the sake of the other, but fate doesn’t really care what you think.
Between desire and possible killers, can they learn that they are stronger than they thought they were? Can they live one day at a time or will they let the very real thought of life separate them?
And death, don’t forget death. If they can overcome their obstacles, the biggest being what they refuse to acknowledge. Then there’s a chance happily ever after will apply to them after all.
