Notes on The Sparrow by Mary Doria Russell
I found the book engaging but it seemed to lack the really big payoff that it promises in the begining.
As it is a metaphor for the New World, it does suffer from a bit of SF cliche. The world is very Earth-like, both intelligent species are vaugely hominid, they can learn English, and we can learn their languages, they come in male and female sexes exactly anagolous to earth. The aliens are fairly primative so that the contact is on about the same technological level as the European/American contact.
And because Russell wants to tell a story resembling that of a missionary party, the contact is a little stupid, in my opinion. Instead of pulling their asteroid/spaceship in orbit above some city, and radioing "take us to your leaders", they land in the wilderness (undectected! Do they have no telesopes on this planet?) and make contact with a rural village. I do not think this would be my first instinct.
It reminded me, in a way, of Charles Pellegrino's Flying to Valhalla, but probably just because that book also deals with relativistic travel to Alpha Centauri and first contact (the biology's a little more believable in that book).
It also has more than a little in common with James Blish's A Case of Conscience, though the author claims not to have read it. She didn't really set out to write a science fiction book, so I believe that.
Here's some links about the book:
