Francisco is ten years old. Exactly ten. And thanks to a very unfortunate sneeze, he has just landed 67 million years in the past. Armed with an oversized backpack, a cheese sandwich, and a lot of books he's actually read, Francisco must navigate the Age of Dinosaurs — where the plants are enormous, the predators are real, and a newly hatched baby dinosaur named Pebble has just sat on his foot and decided they are best friends. Getting home should be simple. It never is. Francisco and the Thunder Lizards is the first book in The Francisco Chronicles — a time-travelling adventure series for curious, brave readers aged 7–11 who believe that knowing things is a superpower.
