Florkas; the demon attack

So this is a fantasy action book, with a little bit of horror in it. And it's in Finnish.

It tells about the time when Florkas and humaus still lived here both, but were allready separeted. For us humans the year is 1375, but for Florkas; it's 105 068. Demons have been bannished from earth 2000 years ago, but now they have come back. This book tells about how Florkas try to survive under demons attacks and still hide from humans in their land that have been hidden and aparted from human's lands by a canyon and magic.

And I'm gonna translate this to english someday
