Beautiful Darkness by Fabien Vehlmann and Kerascoet (2014)Read about the other entries on the list.
Cute characters, taking tea, are suddenly surrounded by dripping gore. Ah – turns out they are living inside the body of a dead girl in a forest. They climb out of the skull to find lots of tiny companions, wandering about. Trying to set up a new community to survive in the woods is challenging. They forage for food, build new shelters, and interact with the woodland creatures, sometimes trying to befriend them, sometimes killing and eating them. Nature takes its cruel course, picking off the characters one by one as they start to squabble and kill each other.
