The thoughtful and elaborate opening of a middle-grade trilogy opens the doors to the mysterious Grimhill sanatorium, where secrets and dangers lurk both on the labyrinthine corridors as well as in the surrounding forest.

Oskar is a perfectly average boy living with his parents in the red brick house by the biggest market square in the city. Everything changes when he is diagnosed with a serious illness. His parents send him to the remote Grimhill sanatorium, which from the very first moments feels suspicious and off-putting – and the staff don’t make it better. It seems like they are hiding something. Together with his new friends Robin and Vilma, Oskar gets pulled into a compelling adventure as they try to find out what is behind the ominous voices in the night. And what is hiding within the cold forest which seems to enchant the children?

The Secrets of Grimhill: Seven Lily-of-the-Valleys begins an exciting and warm trilogy where nothing is what it seems.

“After reading the first part in the trilogy one feels as if the secrets have only been scratched a little [and there’s more to come]. Despite the exciting and even unpleasant events the book leaves one with a pleasant feeling, and one looks forward ot the next part with curiosity.”
