I had high hopes for Gregory Benford's In the Ocean of Night. I had enjoyed Artifact quite a bit and was hoping for more of the same. The overall problem with the book is that it starts well and then declines, slowly but surely, until the end. By the time Bigfoot shows up, things are really pretty bad. (I kid you not about Bigfoot.)
Books about the unknown are supposed to get more interesting, fascinating, and wondrous the further you get into them, not less.
This is the first book of a long saga, a saga I won't be following.
I haven't read this, but my husband did. He enjoyed the series very much. I have all 6 books if you want the whole series at once.
I really enjoyed this book, read it in two nights.
