What makes characters so unforgettable? Quirks? Sense of humour? Their reactions to the situations they find themselves in? In a recent review, a reader hoped I would write a second book using the characters from In the Shadows of Angels. That could be a possibility, but what made that reader love those characters?
Because these characters are nothing more than human. No Peggy Sues.
The best advice I ever read (or was told, I can't remember) is to make the characters your best friends. If you wouldn't mind being their friends, more than likely, the reader wouldn't either.
Sorry about the pics posted here. Gee, I had to post something, so why not gorgeous men?
