My only complaint about "Days" is that the two main characters from "Peeps", Cal and Lacey, play very little parts. But they do make an appearance, and play important roles in finishing the explanantion that started in "Peeps". But "Days" is a great read that you are sure to enjoy if you liked the first. I recommend starting with "Peeps" so you have all the background information (the scientific explanations are in "Peeps"), but I think you could reads "Days" as a stand-alone and not be too confused.
