Eva and Hm

The story

After the death of her grandfather, young Eva had shut herself off from the outside world. Worried about her mental state, her parents send her away to a summer camp near the town of Krapina, one of the most famous paleoarcheological digsites in the world, where she is promptly bullied by a boy named Marko. Whilst running away from him, she accidentally stumbles across a portal that takes her 40 000 years into the past. There she befriends a young neanderthal boy named Hm, but things soon complicate when he's attacked by a member of a Homo Sapiens tribe.
