What's Next? (2)

What's Next is a new meme hosted by Iceybooks, and you can participate!
Every Thursday select three-five books that you want to read but can't decide which one to read first.
So here are the books I'm trying to choose between, along with their first sentence and reason they're on my TBR. Vote for which one you think I should read next in the comments!

Here are the three I'm trying to decide between right now. If you want a synopsis, click on the book cover and it will either take you to Indiebound. Let me know your votes in the comments!

Skylark by Meagan Spooner

First Sentence: "The din of the clockwork dawn was loudest in the old sewers, a great whirring and clanking of gears as the artificial sun warmed up."
Why it's on my TBR: Honestly? The cover is pretty.

Tiger Lily by Jodi Lynn Anderson

First Sentence: "She stands on the cliffs, near the old crumbling stone house."
Why it's on my TBR: Love everything Peter Pan.

Throne of Glass by Sarah J. Maas

First Sentence: "After a year of slavery in the Salt Mines of Endovier, Celaena Sardothien was accustomed to being escorted everywhere in shackles and at sword-point."
Why it's on my TBR: Fantasy. Assassins. Awesome.
