I am actually considering reading the books. Does anyone know how close they overlap with the show?
Very much recomend to read the books. Your imagination will give you a better resolution than any TV can produce.

In terms of...
At least there is a second season.
They are progressing very slowly through book one with the story. They could theoretically make 6 Seasons out of the currently 3 existing Books (where the 4th book is I think already in the making). Though Book 3 might be also compactivied into 1 Season potentially.
(There is also a Book 1.5 / Anderson Station ... which is kind of a short add on novel)

If you then enjoyed those books and dont know what to read till book 4 comes out I recomend to jump right into
Frontiers Saga Book 1 - 16
Anyone that I know that read Episode 1 got instantly captured by it and fell into a reading marathon/frency till episode 16.
