    Seems like there could be a sequel to Genome with how it ended. I hope so am a huge fan of Peyton & Des. Getting ready to read the stand alone books. I’ve read all of the other series.

    just finished pandemic, good read.

    luckily i read it before genome, because it’s nearly impossible to tell which is first when you have them both in hand. it’s not evident, not clear.

    why is that? why not make it plain which comes first?
    they both have the same publication date.

    is it a marketing angle? just wondering.

    thanks again, going to read genome now.

      Hi John,

      Actually I believe the publication date that Amazon lists at the title of the book (I assume that’s where you are seeing it) is incorrect. My own records have Pandemic released on April 2017 and Genome on October 2017.
