Took me a while to finish this one. It is an interesting story, told in 1st person, and despite the allusions to military sci-fi, to combat and action, there isn't a lot of it in this book. What you do get is a story of twists and turns, supposition, leaps of faith, confusing and in-depth science... sometimes it it is harder than it needs to be work out what is happening, but it all draws to a nice conclusion (which isn't a surprise).
Sometimes it is just good to delve into Sci-Fi, and this is 80s Sci-fi.
