The Martian - Andy Weir. Story of a lone astronaut stranded on Mars. Unable to put it down, very well written and paced until the end where it seems a bit rushed. The main character seems a little too fun and geeky to be true.
Coming Home - Jack McDevitt. Seventh book of the Alex Benedict series, very well written, but nothing new and not as good as some of the previous books. Rounds off the story well, and connects it back to the first book (that I originally read when it was published twenty-six years ago!). No one does sci-fi archaeology adventures mysteries like Jack McDevitt.
Ancillary Justice & Ancillary Sword - Ann Leckie. The last surviving body of a warship's distributed AI sets out to kill the emperor of known space after she orders the ship's destruction - and uncovers a galaxy spanning cold war between the Emperor's distributed consciousness that goes hot due to his actions.
I enjoyed both books, has some clever ideas and interesting characters & background, but I can see why people are very Marmite over this book. Viewpoint jumps around a lot, back and forwards in time, and the fact the main character doesn't have the language to discern sexes means that every character is referred to in the feminine. It can be hard to follow what's going on, and while lots of things happen in the second book, the main story hardly progresses at all.
Read a lot of Andy Remic. He's like a 30's pulp author, but he does all kinds of mad action sci-fi, a lot of which made me laugh. How can you argue with a man that creates a character called Franco Haggis?
The Dark Defiles - Richard Morgan. I love every other book that Morgan has written, so it was some dismay when I found that he'd got a fantasy trilogy on the go. This book rounds out the series with a lot of pages, though some of the ending is deliberately left ambiguous. I don't generally do fantasy, but the quality of Morgan's writing, characters and backgrounds is of it's usual stellar standard, and it turns out to be a nominal SF book at the end. I was glad to read on his blog that he's got these characters out of his system and will be returning to hard SF next time around. Bring back Takeshi Kovacs!
The Rhesus Chart - Charles Stross. It's a Laundry Book from Charles Stross - 'nuff said. This time out top secret IT admin/apprentice Eater of Souls takes on vampires that aren't supposed to exist, even though they are a hothouse banking research group in the City of London, run by his nightmare ex-girlfriend. A lot of people die.
The Causal Angel - Hannu Rajaniemi. Last of the Quantum Thief trilogy. Clever and mindbending, but sometimes hard work. It reminds me of early Iain M Banks with a large portion of 1001 Arabian Nights mixed in.
Extinction Game - Gary Gibson - ultimately, I found this somewhat disappointing, and the idea is done much better in the Long Earth books by Stephen Baxter & Terry Pratchett.
I've just started Peter F. Hamiton's The Abyss Beyond Dreams, but I'm wondering if I've lost interest in the Commonwealth, especially if (like the previous Void books), half of it takes place in the pseudo-fantasy setting of the Void. It's not grabbing me in the first hundred pages. These mega space operas are all well and good, but when are we going to see the sharpness, pacing and cleverness of his earlier Mindstar books?
