The only way to review the collection is to review each of the individual stories, so here I go:

1) Turing's Apples, by Stephen Baxter. I normally enjoy Baxter's work, but this one misses the mark, a bit. 6/10 and an inauspicious start

2) From Babel's Fall'n glory we fled, by Michael Swanwick. A well-written, impressive, story about the survival of an alien culture in the face of internecine wars. 8/10

3) The Gambler, by Paolo Bacigalupi. The first really hard-hitting, impactful, story in the set. A story that foretells the current age of clickbait media and false news, but never lets go of the real stories behind them all. 10/10.

4) Boojum, by Elizabeth Bear and Sarah Monette. A tantalizing glimpse into a world that we could spend many further novels reading about. Space pirates! Living ships! Head-hunting aliens! A decent story, but it leaves me wanting more background about the universe. 7/10

5) The Six directiosn of space, by Alastair Reynolds. Alternate future history (now that's a mouthful) about space-faring mongols finding out that there are many divergence paths in the universe....8/10

6) N-words, by Ted Kosmatka. No, these N-words aren't what we would normally think of, but they're proof that discrimination is as old as humankind.....literally. 8.5/10

7) An Eligible Boy, by Ian McDonald. Ian McDonald has done wonderful things with his stories of near-future India, and this is more of the same. In an Indian where the gender ratio is so skewed, some men will take any advantage they can get....but can AIs be suitable matchmakers? 9/10

8) Shining Armour, by Dominic Green. A cute little story about an ancient, barely working, suit of battle armor, and the old man who is its caretaker. 8/10

9) The Hero, by Karl Schroeder. This one is almost more fantasy than sci-fi, but its attempt at a world is marred by the pacing issues throughout. 5/10

10) Evil Robot Monkey, by Mary Robinette Kowal. I didn't like this one at all. It's short and doesn't do anything with its characters, really. 3/10

11) Five Thrillers, by Robert Reed. Tracking a super-soldier....make that an amoral super soldier....through the evolution and proliferation of different types of human. Quite interesting. 9/10

12) The sky that wraps the round, past the blue and into the black, by Jay Lake. Well written, but ultimately not catchy. Evocative, but not emotional. 7/10

13) Incomers, by Paul J. McAuley. Young adult fiction, but well done! 8/10

14) Crystal Nights, by Greg Egan. The problem with Playing God with AI is that the things you have to do to make a true AI might be remembered later on....9/10

15) The Egg Man, by Mary Rosenblum. I do love post-apocalyptic near-future Sci-fi, and this scratches that itch quite nicely. Although, it does get a little convoluted near the end. 8/10

16) His Master's Voice, by Hannu Rajaniemi. Er....what?! This story makes.....little sense. It's not bad, just weird. 6.5/10

17) The Political Prisoner, by Charles Coleman Finlay. I'm not sure where the sci-fi part of the story comes in, but otherwise it's an intriguing gulag story. I quite enjoyed it. 9/10

18) Balancing accounts, by james L. Cambias. It's interesting to hear a story from the robot's perspective. 8.5/10

19) Special Economics, by Maureen F. McHugh. Not so much a science fiction story as a story about wage mistreatment in China, really. This stuff goes on in the present day and we should all be concerned about it. 9/10

20) Days of Wonder, by Geoff Ryman. genetically modified animal-humans (?) try to rebuild their society, which means cooperating with their longtime enemies. Good, but could use more background or exposition. 7.5/10

21) City of the dead, by Paul McAuley. I liked it, but I'm still not sure what the point was. 7.5/10

22) The Voyage Out, by Gwyneth Jones. Condemned criminals learn about each other before being forced to land on another planet....somewhere. 7/10

23) The Illustrated Biography of Lord Grimm, by Daryl Gregory. Supermen exist, as do super-villains, but what happens to the ordinary people? A topic similar to that explored in "Age of ultron", though in a bit more depth. 8/10

24) G-men, by Kristine Kathryn Rusch. J. Edgar Hoover dies in a...shall we say, compromising situation, and the FBI has to investigate the killer. 9/10

25) The Erdmann Nexus, by Nancy Kress. Old people begin to form a super-consciousness, capable of both amazing and horrifying acts, and a retired physics professor must unravel the choices that led up to that moment. 9/10

26) Old Friends, by Garth Nix. It could use a bit more background, but overall I enjoyed it. 8/10

27) The Ray-Gun: A love story, by James Alan Gardner. An excellent story about a ray gun...and how it impacts the life of the young man who finds it. 10/10

28) Lester Young and the jupiter's moons' blues. Jazz in space....and a group of aliens who are thoroughly allergic to Thelonious Monk.

29)Butterfly, falling at dawn. By Aliette de bodard. This author has had another story published in the year's best (the completely uninspiring "The Days of the War, as Red as Blood, as Dark as Bile"), but this one is actually quite a bit better. It's a murder mystery in an alternate-history mexico, one ruled by the Chinese. 8/10

30) The Tear, by Ian McDonald. Evocative, certainly. But....I just don't understand it. Perhaps I'm missing something, perhaps I'm not bright enough to see it, but this has bits and pieces of brilliant story with nothing to hold them together or make them coherent. 4/10. ( )
