Description:

Grab a torch, take a deep breath, and prepare to enter the most mysterious castle Mouse Island has ever seen! In this extra-special Geronimo Stilton adventure — the 100th book in the original Italian series — our timid hero is hauled away from his cosy writing desk by his fearless sister Thea and prank-loving cousin Trap. The trio has just stumbled upon a long-lost castle built by the founder of New Mouse City himself, for a beautiful bride hidden away in legend. Surrounded by twisting white roses and crackling with secrets, the castle holds exactly one hundred keys… but only ninety-nine doors. Which mysterious room does the hundredth key unlock — and what hidden truth is waiting inside? Packed with puzzles, full-colour illustrations, and a bonus Mini Mystery plus pages of cheesy jokes, this is mouserific storytelling at its very best.
