About this book
When a priceless piece of mouse art goes missing, mild-mannered newspaper mouse Geronimo is swept into a top-secret mission—complete with gadgets, disguises, and plenty of cheesy cliffhangers. With help from his friends and family, he must think fast, follow clues, and outsmart some slippery suspects. The playful fonts, colorful illustrations, and short chapters make this a great pick for developing and reluctant readers. Fans love the humor, fast pacing, and lovable, nervous-but-brave hero.
