There are a lot of books out there with FBI/Special Agent heroes and heroines. Personally, I like the Regular Joe (or Josephine). I have no idea what it's like to be an uber cop, but I connect with characters who are normal people thrust into abnormal situations: the soccer mom who's kids are threatened, the accountant who accidentally discovers his company is laundering money for the mob, the lawyer who discovers his client really IS guilty.
It's easy for readers to put themselves into a regular Joe's shoes and wonder, what would I do?
The Firm by John Grisham is a perfect example. Mitch is just a promising young lawyer who's just scored his dream job-until he learns what the firm is really up to and that they have him by the short hairs. Harlan Coben is another writer who pulls the reader in with his ordinary person characters.
What type of character's do you like?
