One would think that picking names for your novel's characters is not a complicated process. You wing it, names coming out of your imagination or the top of your head in the moment. For my novel "Revoked" however a large number of my characters started life with different names;
Lily Maloney became Jasmine (Jazz) Breslow;
Zachary Daniels became Zac Warren;
Jacob Walsh became Jacob Cache;
Jessie McKenzie became Danny McKenzie;
And there were others. If I tried to explain why I changed some of the character names after the first two or three drafts, I couldn't do it. It just turned out that way. There is one prominent exception however; the main protagonist in "Revoked" was changed from Brandon Clay into Cam Clay for a very good reason.
Cam Clay, my tortured and flawed police detective was named after my nephew Cameron Pachan. Although there are very few similarities between the two Cam's, the name change was largely done as a tribute. During the early stages of writing and planning "Revoked", Cam Pachan was battling through a leukemia diagnosis as a very brave and courageous 17 year old man.
If "Revoked" becomes a series, I hope that Cam Clay become synonymous with bravery and courage much as Cam Pachan has done in his life; and takes his place among my all-time favorites like Harry Bosch (Connelly), Alan Banks (Robinson), Logan MacRae (MacBride), and John Rebus (Rankin).
