"Sirius" was a delight.
Definitely, an anthology for dog-lovers was needed; there had been five "Catfantastic" ones, after all -- so, finally, the dog has had its day and we're reaping the benefit.
The best and most memorable stories here were by India Edghill (a historical fantasy about Charles II's dog), Julie Czerneda (an alien learns to appreciate a dog), Elaine Quon (a funny story about a dog/human bodyswitch), Michelle West (good short story using the backstory from previous published novels), Doranna Durgin (fine short story using backstory from previously published novel(s)) and Rosemary Edghill (an alternate-world adventure where dogs have a far greater role in society and security; by the way, the last line here was absolutely perfect).
There was only one story I'd call marginal here, and that was the leadoff story by Tanya Huff. I'd not have expected that, as Ms. Huff is one of my favorite writers, and is an excellent short story writer. However, this story (about a dog searching for its long-lost master; the s/f spin is that the master was lost through a worldgate) felt flat, almost as if Ms. Huff had tried too hard or something, and I would have appreciated the touches of humor Ms. Huff usually brings. Instead, this story was almost too downbeat, and even the somewhat happy ending couldn't completely save it. I felt this story ("Finding Marcus") was more depressing than Jane Lindskold's, where at least I knew going in that her story would be dark fantasy.
But out of sixteen stories, to have only one I considered to be a clinker isn't bad, which is why this anthology gets four solid stars and a recommended tag.
P.S. I hope another anthology about dogs is planned, because as well as bringing back all the authors from this one, I'd like to see a story by Jennifer Roberson (she of the "Cheysuli" universe), as she's also one of my favorites -- and the only one I expected to see here that I didn't!
