The Vanished Reindeer - Grace E. Robinson - Bog

Lapland, northern Finland
Land of the frozen tundra and the midnight sun...
Land of the Sami and their reindeer...
And a mystery...

How does an entire herd of reindeer just vanish?
Police detective Lyylia Niiranen thinks the clue lies in the lake.
Reindeer herder Ávgos Heikkilä wants his animals back so he can support his family.
American scientist Shaun Abernathy is just there to study the northern lights.
But something else has other plans for them.

There's magic beneath the lake, and these three strangers find themselves in Pohjola, a world of tales from Finnish mythology brought to life. As they befriend the woodland people and their sorceress Queen, they find a deeper mystery. This world was once a land of magic reindeer, but they have vanished.
The evil king of Ice-Dark has his own plans for Pohjola and the Queen, for the northern lights that dance in the sky, and for the humans. The battle to come is to save not only Pohjola, but maybe even Earth, as well.

And then there are the reindeer...
