It's very good, reasonably hard SF (i.e. it tries to avoid space opera tropes such as artificial gravity, etc.).

After watching the Netflix series, I was curious about the original. The TV show is curiously close at recreating individual scenes very faithfully from the book, but simultaneously strays far from the characterizations of the cast, peppering the show with somewhat unnecessary tension that's also not in the source material.

Overall, I prefer the book. It does a much better job at keeping the plot on track, the characters relatable, and the reveal is far more intriguing than the TV show lets through.

The first season covers about half of this first book, but either invents a new plot line, or lifts it from a later book (I don't know yet).

Stick to the books, then watch the TV show for the visuals.
