Good, a classic?,
This review is from: Mission Of Gravity: Mesklinite Book 1 (S.F. MASTERWORKS) (Paperback)
As the books description says, this is a description of a mission by humans on a hostile alien world. Actually, humans are peripheral in the story. The heros are actually aliens similar to caterpillars.
It is a great book because it describes the alien world so believably - you really get drawn in. The book moves along briskly, and even though some heavy science (gravity) is thrown in, this didn't put me off (I don't like too much hard science in my SF).
Well worth reading if you are a fan of SF books, and a good addition to the SF masterworks series.
