This question already has an answer here:
I remember reading a young adult series probably 10 years ago, with quite a few books in the series. My memory is very fuzzy but I will try my best. One thing I remember above all else is that it creeped me out.
In the first book, a colonizing space ship leaves Earth with maybe 100 people, perhaps with some sort of cryogenic sleep. The ship lands on an unkown alien planet, where I remember there was something dangerous about the grass or environment. In successive books, colonists even die or disappear. In one book there is a scene referencing the tower of babel (I think?), hellish terrain and creatures like imps.
I vaguely remember a protaganist becoming pregnant, and that being an important theme, but I could be wrong.
A lot of the series reminds me of a Salvador Dali painting or something, very abstract with a hint of creepiness. If I can remember more I will edit the question. Sorry my question is so vague.
