Read Red Rising and Throne of Glass first!!!
Throne of Glass was pretty good so maybe start with that one? Red Rising and The Coldest Girl in Coldtown both got good reviews, so you really can't go wrong with whatever one you pick, so enjoy!
Man, you are going to have a fabulous January with that book line up. As for which to read first, I second Kami: Definitely read Red Rising and Throne of Glass! This is definitely a great time to pick up Red Rising, since its sequel gets released on Tuesday. And I just love the Throne of Glass books - except for the first book. I weirdly didn't like the first book and almost didn't continue the series, but I'm so glad I did since Crown of Midnight and Heir of Fire were two of my favorite reads of the year.
You've had a good start to the month indeed! I hear good things about Red Rising but Thrones of Glass was a DNF for me so I can't really give you any recommendations. Looking forward to reading your reviews though.
I love that you're reading more! Yay! You've read more than me this year. ;)
Ooh Throne of Glass! I would start with that first, the series is great. ToG is actually my least favourite of the three books we have so far, but it's still really good. I've heard a lot of good things about The Coldest Girl in Coldtown too, though I haven't read it yet (I am a huge fan of Holly Black's Curse Workers series though).
I have yet to read Red Rising, but I've heard amazing things, and Throne of Glass was really pretty great. Not my favorite YA fantasy, but very entertaining. HAppy reading!
I've been meaning to read THE COLDEST GIRL IN COLDTOWN for forever, but still haven't gotten to it. THRONE OF GLASS is supposed to be awesome. RED RISING, I think I have on my shelves somewhere ... I'm no help, but I'll be interested to see what you think of all three!
