Series I want to read

I know, I know, we all have the same problem: an ever-growing TBR and there are so many books on mine - most of them series, because I love it, when there is no end to a book (or at least when it feels like there is none). So that's what I want to talk about today: Series I want/need to read!
(as always I will link the Goodreads-pages of the books for further information)

1. A Court of Thorns and Roses (by Sarah J. Maas)

You all know, that I loved the "Throne of Glass"-series by Sarah J. Maas and that's why I came to the conclusion, that I have to read all her other books! I already own the first two books in the series, even though I have no clue what they are about, but they can only be fantastic, if they are written by Sarah! So, I am ready to go! (and I will, as soon as I finish "Empire of Storms")

2. The Illuminae Files (by Amie Kaufman and Jay Kristoff)

I heard so much about those books, that I just have to go and pick them up, when I have any money to spare! Also, they seem to have such an interesting concept with the Mails and all - I am really excited to read them soon!

3. The Conquerer's Saga (by Kirsten White)

I first saw the cover of "And I Darken" on Tumblr, and I fell in love (I mean the cover with the girl on the front), since then I heard some Booktubers talk about the series and that only proves my point, that I have to pick them up!

4. Passenger (by Alexandra Bracken)

Another book that I loved the cover of and which I have to pick up because of that!

5. Discworld (by Terry Pratchett)

I don't even know, how I found out about this series, but when I read its reviews, I knew I had to pick it up, and I will - soon!

Also worth mentioning:

Shades of Magic (by V. E. Schwab), all of the Harry Potter books (by J. K. Rowling), The Paper Magician Trilogy (by Charlie N. Holmberg), the Rebel of the Sands series (by Alwyn Hamilton) and The Wrath and the Dawn Duology (by Renee Ahdieh)

Have you read any of these and which series are one your TBR-list? Let me know in the comments!
