Mandigo and the Hellhounds by Anders Reemark

The first book in the Mandigo trilogy.
When eight-year old Mandigo finds a baby on a raft in a river, he saves it but, when he tries to carry it back to his village, he is stopped by a large stag. The stag forces Mandigo to take the baby deep into the forest, and soon other animals join the curious trio…
Thus begin the adventures of Mandigo, a boy who spends his days toiling in his father’s mill in the mediaeval village of Oakhill. Little does he know that his life until this moment has all been one big lie. When the cataclysmic event known as the Storm wreaked havoc across the world many years before, it changed the landscape and released violent magical forces.
By his twelfth birthday, Mandigo has discovered that he has become the unwitting focus of those magical forces. He must quickly learn how to deal with them in order to save not only his own soul, but also the lives of everyone he loves.
The problem is that the Hellhounds are already on to him…

Mandigo and the Hellhounds, was originally published in Danish (as Mandigo og Helvedeshundene) by LSe in 2015. Keen to see the story reach a wider audience it has been translated into other languages and this English translation is by Nina Sokol.
