Witch King by Martha Wells concerns the kidnap of the demon Kai and his best friend, and them being imprisoned under the sea (water interferes with a demon's powers). He gets free, frees his bestie, and they then try to discover who did this to them, and why. There is a LOT of world-building in this one and little enough hand-holding. You'll just have to wait and be patient to find out what some things are, because nobody is going to do the 'as you know' info dump. The magic systems are interesting, to boot. The chapters semi-alternate between the present and Kai's revenge-quest, and some seventy years in the past set during a genocidal invasion of the land by mysterious outlanders. There's more to come in this series, but you can read the first book without feeling like you're been cheated.
Necrotek was a fun read. So, when all the previous tests of teleportation technology have left entire stations turned inside out and worse, maybe put the brakes on that tech for a time? Nah! Mankind has moved out into space but remains trapped in the solar system, hence trying to develop a way around that. The first firing of the Warpline gun goes disastrously, marooning our heroes on the other side of the galaxy. As the station reels from the disaster, however, other things start to happen. Strange things. Impossible things. And we meet the stuff that lives on the other side of our galaxy: the spawn of the Outer Gods, the shoggoths. Shoggoths with starships. 'nuff said.
I liked this, perhaps less well than I like his Joe Ledger books; I put that down mainly to the ensemble cast.
I started on
Capes: Rising Tide, and I'm a few chapters in. So far, I really like it. It's a new series and the perfect jumping-on point for the Capes world. Several years ago, Something Happened, and now people occasionally get super powers. Fast forward several years and the world has begun to deal with this fact. The world building is rock-solid, and everybody want to run a superhero universe should check it out. It's somewhat more grounded than normal comic books, but that is not the knock I usually think of when I hear the word 'grounded'. Shall we say that some of the implications have been thought out a little better than in most superhero lit, and go from there. There are some references to the main Wearing The Cape series, particularly the last two books, but you don't need to have read them; things are recapped briefly in news stories, chapter beginnings, and dialog. I haven't read the last three books, and I'm not feeling like I'm missing anything big, yet.
So far, so good.
