Start with his first "Harry Bosch" (the character series) novel and then work forward.
Your local library probably has access to all of them (ours does).
What's interesting later on in the serious is that the "The Lincoln Lawyer" ends up being Harry's half brother and they work a few cases together.
If you like detective novels you might also check out the "John Rebus" series by Ian Rankin and the "Kurt Wallander" series by Henning Mankell.
