Maybe simple lists of characteristics would be easier to understand. Since the series is a continuing story, I'll toss in things from all three books. Randomly, without explanation.
Settings: An island in the middle of the Barents Sea, Siberia, a Finnish Forest, the marshlands of northern Scotland, Otherwhere, the lost island of Ultima Thule, the Hall of the Mountain King.
Characters and Things: A group of witches, a bunny named Teddy, a sorceress, a polar bear, orcas, trolls, vampires (two varieties), werewolves, Siberian tribesmen, elemental spirits, an evil Shaman, a shipwrecked man who'd been disemvowelled, mutants, skrats, the darts champion of Scotland, a has-been goddess, a unicorn, a stag, a hound (green), a black giant, a cat fairy, a sentient ultralight, various flying brooms, a Vespa scooter, snowmobiles, and two kinds of railroad.
Now you know why it's hard to explain the books in a brief conversation.
