This very special edition features a full-length adventure celebrating Geronimo's 10th anniversary of writing books, PLUS thirty-two pages of extra content!
Grandfather Williams was throwing me, Geronimo Stilton, a party for publishing books for 10 years! But he also asked me write a new book especially for the party, and I barely had any time. Then, right when I was about to send it to the printer,
my computer was stolen. Cheese niblets, how terrible! It was up to me and my friends to find my computer and print my new 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?
