  1. Wow, I‘ve only read part 1 of this story but I already love it so much!
    I was very excited for the rest but it seems as if there’s a problem with the quantumbang website … When I click the link it says that the website is not working at the moment :((
    Hopefully it will be fixed soon because I can’t wait to read part 2 and 3

  2. Hi, I really love your story! Unfortunately I can’t finish it as there seems to be a problem with Quantum Bang, it keeps coming up with internal server error. Do you know what’s going on? Thanks.

  3. I love this story. This has to be my 5th or 6th read-through since it dropped on Quantum Bang, and each time I read it I find something new. It’s my current favorite story of yours. The “favorite “ title tends to shift around, but this story has held that position for months now. 🙂

  4. I just found these pretty covers and I love how they make me want to re-read the story…in fact, I think I’ll start my weekend early lol. Hope you have a good one.
