Presumed Missing — Nancy K. Wallace

Abby Spencer's favorite book is missing from Evergreen Library! One by one, other books start disappearing, too. When Abby sees a suspicious stranger run out of the library with copies of the missing books in his briefcase, she jumps to conclusions. Now the Book Bunch is on the case! But things aren't always what they appear to be. Can they track down the book thief before more of the library's most popular books vanish?
