Geronimo Stilton is summoned back to the Kingdom of Fantasy, but he finds Blossom, Queen of the Fairies, surrounded by dark fairies and behaving very coldly--and it is up to Geronimo to figure out just what is going on and find the allies he needs to free Blossom from the evil spell that is affecting her.

When the Cavemice discover a giant oyster in the lagoon near Old Mouse City, they call on Geronimo Stiltonoot to help them fish it out of the water before the saber-toothed tigers find the pearl.

All the mammoths have fled Old Mouse City! It's a total cat-astrophe! Not only because mammoths are valuable allies of the cavemice, but also because without them, the cavemice can't make mammoth milkshakes, their delicious national drink. Geronimo Stiltonoot must embark on a daring journey to find the mammoths...and avoid going extinct before he gets back!

When their cousin is stung by a cavefly and falls into a deep sleep, Geronimo and Thea set out in search of the rare pink stinkrose, whose petals are thought to provide a cure.
