About This Book
The cold, rough stone crunches under George’s trembling fingers as he breaks the dragon’s head from the museum wall. Suddenly, the air crackles with ancient magic, and a giant stone Pterodactyl tears free, its silent wings casting shadows that chill the streets of London. In a city where statues hide secret lives, George’s daring act awakens a world where danger and wonder collide, and hope flickers in the darkest corners.
Quick Assessment
Set in a vividly imagined London where statues come to life, this middle-grade fantasy follows 12-year-old George, who accidentally unleashes an ancient power by breaking a stone dragon’s head. The story explores themes of loneliness, courage, and the blurred line between the living and the inanimate. Suitable for ages 9-12, the book contains mild fantasy peril but no graphic content.
