Under the Never Sky Series
I see this as a favorite on a lot of bloggers list. I haven't read it. Its not that I don't want to I just never picked it up. I hope to change that before the year is out.
The Selection Series
I started this series when it first came out and it is one of those that just got put further down on the TBR pile. Obviously I don't remember anything about it when I read it the first time so I am rereading bk1 and planning on finishing it.
The Throne Glass Series
I started watching booktube (youtube) and I saw this book circulating all over the booktube atmosphere. I saw how great it was and realized that I am so far behind on reading this series. The funny thing is...I bought bk one last month and I still have not read it.
The Sweet Trilogy
The Lunar Chronicles
Again, I only read (listened) to book 1 and never went for the rest of the series. I loved book 1 and I really need to finish it.
The Delirium Series
There are so many others that I need to finish or start. I know I'm not the only one out there that does this. Let me know some series that you need to finish or start.
