The Book Bandit: A Mystery with Geometry — Melinda Thielbar

The science club has created a big "book bandit" sculpture in the public library. But how did they get the sculpture in through the tiny library window? The librarians offer a prize to whoever can figure out the puzzle. The kids from Sifu Faiza's Kung Fu School know they can win, but it will take all of their geometry skills plus some unexpected cooperation to size up . . . The Book Bandit.
