I finished reading the original Halo trilogy – The Fall of Reach, The Flood, and First Strike – a couple of days ago. Now I'm reading the first book of the Mass Effect expanded universe: Revelation. I wanted to start reading Star Wars: The Old Republic – Revan but I don't own it and I don't get paid for another ten days, so I decided to start on Mass Effect since I hate not having anything to read. I'm almost always involved in some book or another. I can't remember the last time I went more than two or three days in a row without reading something. So that means I'm not going to be able to read Revan until I finish the four books in the Mass Effect series. We'll see how long it takes me. It took me a month and a half to read Halo, but only about three days to read the last book (First Strike) since I was only reading a chapter at a time.
I'm reading the second book in the Gentlemen Bastard series by Scott Lynch. Lies of Locke Lamora was really good but I'm taking my time with this one.
Zen and the Art of Motorcycle Maintenance And rereading Star Wars Republic Commando: Hard Contact. That series is so fucking good.
Just read Halo: Saint's Testimony. This one was really interesting since it dived into a subject matter which sci-fi stories always stray away from which is the rights of an A.I. A nice little short read worth the $0.99 price for any fan of the series. Now debating whether I want to buy Hunters in the Dark or finish Primordium first.
Very similar theme to the series I mentioned, Star Wars Republic Commando, which gets into the moral implications of the Republic's clone army. I might have to have a look at your book since it sounds a little similar.
You really don't need to know a whole lot about the Halo series to keep up with the short story. Even if you were confused at a certain reference or who a certain character was, you can always just google it.
