I read the first book 10-15 years ago. I always wanted to read the sequels but for one reason or another never got around to it. I was told that the last Season covered all of Book 2, so finally I gave it a try.On another note: I've just finished book 1 of the series, I decided I couldnt wait for season 4 in next summer, I had to read the books to know what is going on. But the book is very different. Its a complete different atmosphere. Way more depressive, introspective, sometimes almost fever-dream like, especially in the early chapters. The books and the show are so different that reading the book is still exciting even if you've already watched the show and I bet after I finished the books season 4 will still be exciting.
Without spoilers, If you found the difference in tone and story between Book 1 and the first 2 seasons striking, the following novels diverge even further, almost like with Foundation. There are however some bits in Book 2 that could potentially spoil some of Season 4 stuff, assuming the show will follow the same overall narrative.
