Title: Revenge of Nébouzat-le-froid - Christine Avel - book
Summary :
Éloi lives in Nébouzat-le-Froid and he doesn't like it. If he had the choice, he'd move across the street, to Nébouzatle-Chaud. At least there they have sunshine, troglodyte caves, and authentic dinosaur tracks. Until the day Jojo, the dog, digs up a bone like no other in the garden. According to Éloi's grandfather, it's a tibia. And not a cow or horse tibia. A hipparion tibia, a prehistoric animal! Excavations immediately begin around the house. Some time later, a second bone appears. It's covered with inscriptions resembling small sticks. Could these be the remains of the very first writing? The curious and the jealous are on the prowl. Night patrols are organized. Soon the museum will open in Nébouzatle-Chaud. We are just waiting for the expert to visit.
