This well-written novella grabbed my attention from page one and held it right through to the end. I read the author's debut novel, A Long, Long Way to a Small, Angry Planet after I finished this one (liked it as well) and can safely state that both share some common thematic elements that I can't do without in my Scifi. These are:
1. I need the characters in my SciFi fiction to be consummate professionals with an unmatched expertise in their fields of specialty. I really can't tolerate books or movies that depict crewmates on scientific expeditions as incompetent, or worse, psychotic. Really. Does anyone think that a mission to space to save mankind, something that, say, took a decade to prepare, would be manned by crew members with personality disorder?
2. Duty. Crews aboard space ships that travel at relativistic speeds have to be unquestionably dedicated to their mission. There is no room for doubt.
3. Sacrifice. Every man and woman aboard ship must put the needs of their fellow crewmen and the mission first.
4. Camaraderie. Everyone must get along. It's a prerequisite to success.
I find that a lot of SciFi writers manufacture drama between characters serving on starships because it's easy, and they're too conditioned to the cliche Hollywood formula to write a story without personality conflicts between characters. If you want to write about conflict between crew members on a Starship, you need to make it entirely plausible. For example, in this novella, an unpredictable incident creates a situation that doesn't seem to have a remedy. The situation leads to an entirely plausible and contagious sense of despair. Kind of like in the movie, Perfect Storm, when the crew of the Andrea Gale ran out of options and knew death was on their doorstep.
This isn't to say I liked every aspect of this read equally. There is a certain Kumbaya element in the author's writing that seems over the top. Imagine you go to friend's house for a dinner party and everyone there is raving about the house and meal to the hosts, and then complimenting each other all night long.
Still, a great book.
