Vanished (Boarding School Mysteries Series)
This is the first in the Faithgirlz boarding school mysteries. Jeri wants to be an investigative reporter but she didn't think the first case she would have to solve would be the disappearance of a school van with six students and a teacher in it. One of the students is her roommate Rosa. Jeri is a sixth grader. She discovers lots of clues and has a lot of suspects. She manages to solve the problem. This is a good middle grade mystery with a definite Christian bent.
