"Breakout star Creepella von Cacklefur is back in another fur-raising adventure! Oh, no! Billy Squeakspeare has a big problem, and he needs Creepella's help. Someone's been digging holes around Squeakspeare Mansion at night, and Billy wants to find out who it is. The dangerous, legendary pirate Morgan Darkwhisker is said to have buried his long-lost treasure near Squeakspeare Mansion years ago -- could he be hunting for his hidden riches? It's up...

When, in the process of testing his newest time machine, Professor von Volt accidently brings a triceratops, Helen of Troy, Attila the Hun, Charlemagne, and Christopher Columbus to present day New Mouse City, it is up to Geronimo and his friends to return them all to their own times and places--without being eaten by a T-Rex or skewered by Trojan warriors.

For the seventh time Geronimo Stilton finds himself in the Kingdom of Fantasy--this time Blossom, Queen of the Fairies, needs him to find the seven enchanted charms before the evil Wizard of the Black Pearl can get to them.

The Harmony Stone has been stolen from the Crystal Castle, and without it the Kingdom of Fantasy is vulnerable to an ancient enemy, The Invisible Army; Geronimo, together with Queen Blossom's daughter, Winglet, embarks on a mission to find the ancient crown which will defeat the Invisible Army and restore harmony to the empire--but they must make it back to the Crystal Castle before it is overwhelmed by the enemy.

"Yes, it's true--I'm a total 'fraidy mouse and the biggest worryrat. In fact I'm the complete opposite of my super-sporty and very brave friend Bruce Hyena. That's why I couldn't believe it when he dragged me off on a series of outrageous adventures to toughen me up. I had to keep reminding him that I'm not a supermouse! Or am I?"--P. [4] of cover.

Once again Geronimo Stilton's pulled into the Kingdom of Fantasy, where he's needed to fulfill the ancient Gemstone Prophecy and prevent Scorcher, the evil Empress of Witches, from obtaining the Royal Sapphire which will give her immense power.

Once again Geronimo is summoned to the Kingdom of Fantasy, and this time he must rescue five princesses of The Kingdom of Lotus Flowers who have been kidnapped by a terrible witch--but first he must journey to the Island of Dragons to find the bravest, the wisest, the silliest, and wittiest, and the most sincere dragons who prophecy says will aid him in his mission.
