Gregor and The Prophecy Of Bane
Gregor is back in the Underland and he has to find a white rat, who will lead the rats in war, and kill it.He is on the road again with his friends on a Quest.
Gregor And The Curse Of The Warmbloods
In the Underland there is a plague which any warmblood will catch(rats,humans,bats etc.).Gregor's mom catches it and Gregor finds out that he is a Rager (a kind of warrior, he kinda goes crazy and his senses heighten).He goes on a quest to find the cure.
Gregor And The Marks Of Secret
Mice are disappearing and Gregor and his friends go to see if they find anything.They find out that the rats are being lead by the Bane(the white rat)and are taking revenge on the mice.Can they save them?
Gregor And The Code Of Claw
The final battle.Gregor thinks that he will die with the Bane in the battle that is coming.He gets close to Luxa, the queen of Underland(officially queen when she turns 16), after he rescues her from the rats.
The last 2 are darker than the rest and other than the romance between Gregor and Luxa in 4 & 5 there is nothing bad an them other than some killing and fighting scenes.They are very exciting!
I really liked them :)
