I'm working on Luna: New Moon by Ian McDonald on the Kindle (think GoT with dynastic companies on the moon) and Blood of Elves by Andrzej Sapkowski for the 'paperback to take to work' option.
For my Historical space I used Dread Nation by Justina Ireland, which is the best book I've read so far this year. The Ballad of Black Tom by Victor LaValle would also count as well, I think.
I have Luna: New Moon on my Kindle too and hope to start it soon. I enjoyed The Ballad of Black Tom as well. Looks like we belong to the same free e-book club!
I finished L:NM early this morning, and it's one of the best books I've read in awhile. The critiques are valid though; tons of characters, freely borrowing words and concepts from other languages with little explanation. I'm getting the sequel from the library, though. Over $15 regardless of format, ridiculous. I love the Tor emails, but I've missed out on a couple books in the delay of checking email and then 'oh, need to log on to the Kindle to get it' and never doing so. We're reading the Murderbot one for book club in December; wanted it and missed....
I pick up a lot of the Tor e-books by downloading to my desktop, and then emailing them to my Kindle. I think I've only ever messed up one book that way. But I have learned to be more selective and not just take books because they're free. That has ended in tears (or, more often, bad language on my part). *grin*
