The Beast Under the Wizard's Bridge (Lewis Barnavelt #8)

What is it about the old Wilder Creek Bridge that makes Lewis Barnavelt so curious-and so afraid? When Lewis and his best friend Rose Rita Pottinger set out to explore the bridge and the deserted farm nearby, they discover shocking secrets—and a horrifying monster. Even Lewis's Uncle Jonathan and the magical Mrs. Zimmermann may not be able to vanquish this ferocious creature! Based on John Bellairs' mystery-adventure series.
