What order does Tim novels go in?

Please clarify which "Tim" you're referring to. Do you mean the Tim series by Walter Dean Myers, which features Timothy "Tim" Walker?

If so, the novels in order are:

1. Hoops (1989)

2. The Beast (1990)

3. Bad Boy (1991)

4. The Door (1992)

5. Fallen Angels (1988)

* Although Fallen Angels was published earlier, it takes place after The Door in the timeline.

If you're referring to a different "Tim" series, please provide more information so I can assist you!
