I enjoyed this book, which had lively characters inhabiting interesting worlds. There is nothing terribly unique about setting or plot, but the style was fresh enough to make it different.
Sirantha Jax has a unique talent which allows her to jump through Grimspace. As a navigator, she is paired with a pilot and, together, they carry passengers and cargo across long distances using ancient beacons and star roads. All navigators like Jax are employed by the Farwan Corporation and they eventually burn out, their minds unable to cope with the continuing stress of navigating Grimspace.
Unfortunately, as the book opens, something has gone terribly wrong with Jax's last flight. The ship crashed, killing everyone onboard included her beloved pilot Kai, leaving only Jax alive and unable to remember what went wrong.
She is sprung from the dubious care of the Corp by March, a mercenary on a mission. Jax is forced to work with him as a pilot to escape the space station on which she was kept and work with his mismatched crew. During the course of the book Jax gets drawn into March's mentor, Mair's, grand plan for free academies for navigators, drawing on the genetic benefits of other races alongside humans and she also begins to uncover what happened on her last mission.
The written style is slightly unusual as it's written in the first person in the present tense from Jax's perspective, but it is well done and has a real immediacy. Fortunately Jax is a likeable and interesting character which makes hearing her point of view interesting. Jax definitely develops and grows as a person in the book.
March is an interesting and compelling character, who has some wonderful moments. Jax has a mental connection with March, so we also get to hear his thoughts in parts of the book, but I'd have liked to have seen more of March.
The developing relationship between March and Jax is well handled and believable as she grieves for her lost lover Kai.
The other characters, particularly Doc and Dina, are entertaining and a twist involving one of them later in the book is clever. I was less keen on Mair and Keri and some of the characters who are met earlier in the book, but I suspect that they will be returned to in later novels and fill out a bit more.
The worlds the plot plays out against are well written and interesting. I liked the idea of them being aware of much less developed civilizations and keeping an eye on them.
In summary, it's a good read and I'll be looking out of the next book in the series.
