A Darkling Sea is in the stores, on the shelves — and in the clutches of reviewers. They have been quite positive, though. We've already heard from the Big Three, but now various bloggers and free-lance critics are weighing in.
Annalee Newitz gave it a favorable review on NPR.
SF Crowsnest has a nice writeup by Kelly Jensen.
The Nerds Of A Feather 'blog has a "microreview" which is longer than most "full length" ones, also very thoughtful and positive.
Koeur's Book Reviews has some nice things to say.
And over at the Qwillery there's an interview.
So far, nobody's really had anything but praise, which is very gratifying. I suppose part of that is just the sheer volume of new books means reviewers don't have time to spend on the books they don't like — unless it's a bestseller or Big Book.
As always, the most important opinions are those of the readers.
