Auzou See you next year volume 2 book

It's summer again. Swann reunites with his friends in the village, especially Léna, his girlfriend. One afternoon, the group overhears a conversation in the village café. An old feud has been going on between two families in the village for a long time, but the locals are not ready to talk about it. All the teens understand is that the secret is linked to the abandoned house at the end of the village. The one that's said to have been inhabited by a witch. Swann and his friends decide to investigate, and too bad if the house gives them the creeps. After all, witches don't exist, right?
