Delaney, Mark. The protester's song

Delaney, Mark. The protester's song [Misfits, Inc. #5]. Peachtree, 2001 [1-56145-244-0]
Thirty years ago Jake's Uncle, Josh lost his leg at an explosion during Vietnam protest. Once night the family goes to dinner and the musician playing reminds Uncle Josh of someone at the protest. That starts a chain of events in which Misfits, Inc (a group of kid detectives) gets involved with an FBI cover-up. In the midst of the story their school librarian resigns over a censorship issue. The buildup to the exciting climax kept me not wanting to put the book down. This 214 page book is #5 of a series concerning this group of detective HS kids. I have a feeling I may be purchasing more of this series.
