Best World Building (Nominations Needed)

What is the best world building (series or book)?  

A lot of books and series involve amazing world building. The setting is fleshed out and immersive. Which world building is the best though?

Come help form our June poll with your reader-based nominations.


The Rules

1- As always, I leave the niggling to your best judgement because I'd rather be inclusive. If you don't think that urban fantasy is really "building" a world since it's just adding a little bit of magic to what's already there, you don't have to nominate such a book, but if you do, that's okay too. Worlds can be our world with a few subtle differences, distant galaxies, or entirely imaginary fantastic realms.

2- You may nominate two (2) worlds. Remember that I am a horrid despotic power hungry beast who hates all life and free will here at Writing About Writing. To encourage reading and reading comprehension I will NOT take any worlds beyond the second.

3- You may (and should) second as many nominations of others as you wish. No book/movie combo will be going on to our poll that doesn't get at least one second.

4- Please put your nominations here. I will take books nominated as comments to this post on other social media; however, they may not get the seconds you need because no one will see them. (Seriously, last month there were lots of great FB nominations that no one saw or seconded.)

5- You are nominating WORLDS, not authors. While everyone will know what you probably meant if you say JK Rowling, many authors have created more than one world, and it may not be clear. (Did you mean Phase/Proton or Xanth when you nominated Piers Anthony?) This also means both of your nominations can be from the same world.

6- As a power hungry dictator, I will be adding Ishiguro's Never Let Me Go to the list.

It's already June 8th, so this poll is going to go FAST. Get your nominations up (and others seconded) in the next week!
