"War of the flowers" is more related to the topic. The land of Faerie is populated by, well, faeries - pookas, trolls, ogres, etc. But it's an industrialised Faerie-land, with guns, mobile phones, laptops, etc (although all driven by magic, and hence all rather different from our world). Good book.

"MS&T" is a great series (if you're a fast reader - it's BIG, and realistically it has long periods of not much happening punctuated by short periods of everyone getting killed) but it's not much related to the topic. The "Sithi" are just your basic elves under a different name.

I'm partway through "Jonathan Strange", but not got round to finishing it yet.
