Kellerby Code by Jonny Sweet

He's found a life worth killing for.

Edward is struggling to hold it together. Just about getting by in a world he cannot afford, scurrying after his friends, doing everything he can to prove his value. But not to worry: the attention of his beloved Stanza and the respite he finds in her ancestral home, Kellerby House, provide all the reward he needs.

Until he realises that Stanza is in love with his best friend Robert, forcing Edward to re-evaluate what those closest to him are actually worth. No price is too high to stop the life he has strived for slipping from his grip. Especially when he won't be the one paying.
