Memory Zero - Keri Arthur Generation 18 - Keri Arthur Penumbra - Keri Arthur

Thanks to Netgalley, I have the other three books in the Spook Squad to review and read as well. I feel so lucky. I can't wait to see how the characters grow the world filled with these unhumans expands, and if there is any romance to fall the main character's way. I'm not sure how I feel about the whiter covers that show more genetics and science, as to the darker ones that seem more as if the main character is guarding the city.  Maybe as I read the series I'll see why the changes are probably more appealing to the book series.
