Sometimes the things we look forward to in life are the small things that regularly delight and surprise us. Such is one of the events I look forward annually, the publication of The Year's Best SF, edited by David G. Hartwell and Kathryn Cramer. It is one of the earliest (and best) of the prior year anthologies published--early enough to accompany me on my late spring or early summer vacation.
I've been reading science fiction for over 50 years. If you know the field, you will know of these editors. Both have extensive experience, having edited many SF books and written significant essays contributing to the field. They can be counted on to select good stories for you.
The Year's Best SF typically opens with a short intro discussing the previous year in science fiction. Then the book introduces select representative shorter SF works by established regulars or important newly emergent authors with a short bio and comments placing the story in context for you, the reader. This year's (15) work follows that model. Of course, each person's taste will vary; in particular, I enjoyed the stories by Vandana Singh (mathematics, other dimensions), Ian Creasey (effect of physical modification for life on other planets), Alastair Reynolds (effect of changes in an alternate universe), Michael Casutt (what if an Apollo crew had discovered evidence of a prior visit), and Mary Robinette Kowal (clone story set in Korea). But know that you'll seldom find a bad story collected here.
If you want to read some of the best short work from the prior year while learning a bit more about science fiction in the process, this is one of the books you'll want to pick up every year.
