The War of the Flowers

I HIGHLY recommend War of the Flowers.

The universe is very similar to the Artemis Fowl style. There exists another world populated by faeries, goblins, dragons and all sorts of folktale and mythological creature. Their world developed a different form of technology based on old magics. Its all very similar to Artemis Fowl but the writing style and plot are very much for adults. Gruesome deaths, full on sex scenes and a regular guy fighting to survive.
