From Norvelt to Nowhere by Jack Gantos
If you liked the Newbery Winner, Dead End in Norvelt, you will love this sequel! After an explosion and a new crime by an old crook Jack finds himself on a mission that takes him hundreds of miles away, escorting his slightly mental elderly mentor, Miss Volker, on her relentless pursuit of the oddest of outlaws.
