Migration is a delightful collection of widely varied bite-sized stories. Reading it, I felt like I was consuming many types of tasty morsels that can be appreciated by so many different palates.
I like how many creative ways different authors interpreted the theme. Many subgenres of speculative fiction are represented as well, including clever blending of genres.
Just as importantly (to me, as a queer person with many queer loved ones), the queer identities of characters range across the spectra of sexualities and gender identities. They also range from being a centermost part of a plot, to part of the worldbuilding, to part of character development.
I also really dig the variety of writing styles and tones to the pieces. Some stories blew me away with their intensity, others made me grin because they were cute/sweet, some made me think "huh, interesting", while still others left me shocked and rereading them in light of a twist ending. I think this anthology has at least a few stories for every taste and mood.
I highly recommend Migration to anyone who enjoys (very) short speculative fiction and is interested in variety - in terms of subgenre, character identities, and tone!
Disclaimer: Migration includes a story I wrote. My rating is for the rest of the stories/the anthology as a whole.
