Finished a few freebies.
Origin by J. a. Konrath is a supernatural-ish/techno-thriller, and a good, quick read. The writing is fairly polished, and grabbed my attention, though I found the idea that the US government would staff the most important secret project in the world with some profoundly broken people a little hard to swallow. Still, it's free at Amazon and well worth a look.
Cloak, by James Gough looked really promising and had lots of positive reviews, including comparisons to
Harry Potter, but I didn't find the writing up to par. It just didn't grab me, even though I liked the idea. I'll come back to this and give it another try later.
The Future Imperfect, by Ruth Nestvold was an enjoyable collection of post-apocalyptic/dystopian short stories. The writing is smooth and very readable, which says a lot for a low-priced book at Amazon. The future science and ideas, while not exactly new, were well thought out and presented. Currently $2.99 at Amazon and worth the price if you like dystopian fiction.
