I just finished reading The Trilisk Supersedure by Michael McCloskey.
Another good read from McCloskey; he really does aliens very well. I particularly liked reading the aliens' internal thoughts, they're just very different from us with strange motivations and cultural drives. They're not just some sentient creatures, they're intelligent, but driven differently. I like that the main characters are nowhere near as safe as they think they are when trusting them - it's very well done.
I also like some of the style of writing, where different individuals drive the different chapters or parts, but with overlapping descriptions of events or time periods It can be really interesting just working out whether parts are overlapping at all, and whether the events are similar, but when things do match up, you get the benefit of different points of view subtly changing your understanding of what is going on.
While the story, tech, ideas and aliens are all really good, again its only the characters that are bit soft, but not in an annoying way. Actually, Cilrith wasn't bad, and the aliens were cool, but perhaps needed more from Magnus and Telisa. More Telisa really :_)
The tech and ideas were really good though, and I particularly liked the reveal of just what Trilisk Supersedure was referring to, right at the end. Excellent. I'll read more for sure.
