I like anthologies. I feel like they give us a chance to see our favorite writers experiment with things for which they aren't known and/or loved. As such, "Strange Reports from Sector M" is a gem, and you should definitely read it.
It's a collection of thirteen short works, broken into two groups: Really Short Stuff, and Not-So-Short Stuff. The Really Short Stuff takes up the first 50-ish pages of the book, and has some of the most interesting experimentation outside of Matt's bailiwick (military sci-fi, if you didn't know). An advertisement for used stars, sci-fi blues lyrics, and other treats greet you here, and can all be easily consumed in a single, long-ish sitting. I'm not a super fast reader, so your consumption rate may vary. The No-So-Short Stuff also has good variety, and I don't want to spoil any of it for you. There are a couple of military sci-fi shorts in here that are pretty fantastic, as well as a short that I would classify as sci-fi/horror, told in first person. I didn't have any problem getting through any one of the shorts in a single sitting, save for The Foeman's Chain (the final, and longest, story in the book). One other note on the writings themselves: as pretext to each story, Matt writes some insight into how/why he wrote each short, which I really enjoyed.
I procured both the printed and kindle editions, although I spent most of my time reading the printed one. The book is VERY well designed, including the cover art, paper stock, even the font selection. You should feel confident getting either edition, as both are high quality.
I'm not sure what else I can say to convince you to buy this book. It's a worthy addition to any sci-fi fan's collection, and can be had for the low-low price of [insert Amazon's current pricing here]. Do yourself a favor a get a copy of this book -- your happiness quotient is sure to increase!
