I haven't read any Star Wars novels in a while, but was intrigued by the blurb on the cover which led me to believe this was about a Jedi working as a private investigator. I was expecting a mystery story. It isn't, but it is an interesting read.
The main strength of this story is the way it leads the reader to empathise and sympathise with characters who have opposing agendas, and makes you want everyone to succeed. The protagonist - Jedi knight in hiding, Jax Pavan - is the best fleshed out of all the characters, and his story provides an interesting look at the fate of a surviving Jedi after the rise of the Empire. Each of the secondary characters - including Darth Vader's personal aide, an ex-soldier, a sentient droid, and an elite assassin - are equally, if not more, interesting. In multi-threaded books, I usually find myself wishing the writer would spend more time on my favourite character, and I often get bored waiting for them to come back, but not so here. As the threads begin to draw together, each different perspective becomes more interesting, and I found myself drawn into the Coruscant underworld, where the last Jedi are hiding and the resistance is beginning to form.
The book's big weakness, I think, is the prose, which is often too bland, at times too descriptive, and at other times not descriptive enough. Sometimes plot development is spelled out to the reader to an almost patronising degree, and repeated as each character learns about it. I would also have liked perhaps a little more character development; being told a character has great martial skills and having to take it on faith until the end is weak writing, when it would not have been hard to work in a demonstration or two. Perhaps over-zealous editing is to blame.
This isn't a bad book, but neither is it a great book. Read it if you feel like spending a couple of hours immersing yourself in the seedier side of Coruscant during the early days of the Empire.
