Fiction

So, I'm writing a story. Not a fanfic, a plain-old fiction that I would like to get published.
There's five (maybe six?) teenagers who are given these special powers to help protect immortal creatures (vampires, werewolves, witches, warlocks, etc.) and there is also this evil group, The Coven, trying to use immortal creatures to wreak havoc on the mortal world and take over both the immortal and mortal world. They also use their powers to stop The Coven, and search for the good immortal creatures and lead them back to the immortal world.
There's a girl, Emma Bennett, who has the powers of telepathy, telekenesis, and super-human intelligence. She falls in love with a vampire, who is charming, overprotective, caring, basically a mix of Edward Cullen and William Beckett, both looks-wise and personality wise. My question is, I have narrowed down his first name to two choices. You tell me which a better-suiting name.
Breviary?
or
Edmund?
