Surf's up, Geronimo is the 20th book in the series.
Geronimo goes out for a vacation--but it takes a unpleasant turn.
Ah, there's nothing like a relaxing vacation on the beach! I would spread out by the crystal-clear water with a good book. What more could a mouse want? At least, that was the plan. But somehow, my vacations never seem to go according to plan. Instead of a beautiful seaside resort, I found myself in a fleabag hotel that was falling down around my ears! Oh, would I ever be able to relax and enjoy my vacation??
