In this roaring alt-history adventure, dinosaurs from a forbidden world have been turned into unstoppable weapons by one of the most ferocious military leaders of all time: Napoléon Bonaparte. In the wake of his crushing victory at Waterloo, Napoléon unleashes his vicious French general Marc Thibault and his brigade of giant battlesaurs to strike terror across Europe. England stands alone, but an invasion is looming. Its only hope is a secret attack led by Willem, a magician's son, deep inside enemy territory, to the very heart of Napoléon's terrifying new army.
In a stunning sequel to Battlesaurus: Rampage at Waterloo, deception and betrayal threaten the mission from its outset, but the courage and perseverance of Willem the "saur killer" and his compatriots lead to a clash of titanic proportions.
