From the bestselling middle grade series, a chapter book about a mouse journalist searching for a missing computer, plus a bonus short mystery and jokes.

Grandfather William was throwing me, Geronimo Stilton, a party—it had been ten years since I published my first book! He wanted me to write a new book especially for the occasion. Then my laptop was stolen right from under my snout. Cheese niblets, how terrible! Could my friends and I find my computer and print my book all in time for the party?

BONUS! After the story, read an extra Mini Mystery adventure: The Lake Monster. When a mysterious monster is sighted in a lake on Mouse Island, Geronimo is called in to investigate! But can he figure out this creature's secret?

PLUS cheesy jokes galore!
