Publisher's Synopsis
Poppy and Lilly enjoy visiting their grandparents. Grandad and Gran take the girls to their favourite lake to feed all the birds and see the wildlife that lives there. It looks so beautiful...
... but the lake has a secret that the queen of swans, Mariah, guards against - something living on the island in the centre of the lake. Something with hard skin and a hundred rat slaves, something very foul-tempered and looking to trap anyone he gets his hands on: the Hippocrocohog!
Can Queen Mariah, Grey the squirrel and the girls' grandparents keep them safe?
