What I have to write next saddens me immensely.
The latest book I've been reading has been Invisible Planets by Hannu Rajaniemi.
Now, Rajaniemi may not ring any bells with you. He's a very new author, with only three novels and a couple short stories out there. Invisible Planets is an anthology of all his short fiction to date, and it's ... unflattering. This is very unfortunate, as his Jean le Flambeur trilogy (The Quantum Thief, The Fractal Prince, The Causal Angel) easily ranks among the best SF of the decade (IMHO, of course). At his best, Rajaniemi writes prose that requires an incredible amount of knowledge to actually parse but told with a poetic lightness that is very hard to emulate. Even if you do not get his references, the imagery he can weave can carry you along just fine until you find something recognizable again.
His short fiction, as collected here, is unfortunately uneven. A lot of it is probably down to Rajaniemi finding his voice (For example, several short stories show signs of aving their beginnings engineered to fit a formula intended to quickly set up a place, time and cast of characters), some of it is down to my personal hangups as a reader (Rajaniemi is a Finn, and there are several stories here deeply steeped in finnish folklore), and as a result, a few stories do miss the mark a bit.
That being said, when the prose shines, it absolutely shines: Stories like Skywalker of Earth, which draws a lot of comedy and drama by taking a modern protagonist and dumping her into a Lensman-ish setting, the Server and the Dragon, a story about a lonely server at the edge of the milky way, or His Master's Voice, about a cat and a dog trying to free their master by becoming the hottest music act in town, really show Rajaniemi at his best.
Overall, if you want to read some experimental stuff (in my previous reviews, I have ragged on novels for being safe; this is decidedly unsafe literature), I recommend this highly. If you really want to experience true greatness though (and aren't afraid of not understanding everything right off the bat), jump into Quantum Thief instead.
