FYI: I've read the first half of the stories in the anthology.
Stirling's contribution I've already mentioned. It's not bad....but nothing really interesting happens (other than a couple of personal details about Heuradys), and the two main characters (Orlaith and Heuradys) basically solve a murder on the fly without investigating, while everyone nods at their wisdom. Grade: C.
Rate of Exchange, by A. M. Dellamonica is a lot better (a couple of new characters, plus Huon Liu, along with a new nation). Nothing earthshattering occurs, and (as usual) Montival makes unreasonable requests that everyone treats as reasonable. B-.
Tight Spot.....is unreadable. Stream of consciousness, first-person POV, weird dialects, and you end up not even knowing if the protagonist is an adult or a child. Oh, and it features the McClintock's...who are basically the McKenzies, but more annoying and less plausible.
At a guess, it takes place a few years after the Change. D-. I've read some of the writer's (Kier Salmon) fanfiction....and it's a lot better than this.
Against the Wind by Lauren C. Teffeau...is not bad. Set in the fall of 1998, and deals with a family working salvage off the Alaskan coast...and features the first chronological appearance of the Haida Raiders. B-.
The Demons of Witmer Hall by M. T. Reiten. If the scientific revelations about the Change in this story are canon....it's pretty much required reading. If they aren't canon...this story sucks, and you wasted an hour reading. B+, or D+, depending on canonicity.
Bernie, Lord of the Apes by John Jos. Miller. Honestly, I'm not sure what to make of this one. Grade TBD.
The Seeker: A Poison in the Blood by Victor Milán. Occult adventures in Mexico. B- for the writing....but the Magic is way, way, way in your face...which is a departure for the Emberverse. The description given of what exactly was involved in the Change also makes the Powers even more asshole-ish than they already seem.
Grandpa’s Gift by Terry D. England....nothing significant happens. A couple of bandit attacks and a CUT-wannabe. Set in Louisiana, at least a century after the Change. C.
Fortune and Glory by John Birmingham. Birmingham gives no shits....so he literally (and openly) recycles some major characters from his "Without Warning" trilogy and plunks them into the Emberverse (while relying on you having read his books, so he doesn't need to provide any real backstory for the old characters in the new setting). This, after Stirling made him King of the Bogans in the Emberverse? F-, Birmo. Bad show.
