Okay, found an app called ReadEra that works decently for book PDFs.
Also...
Holy SHIT, this book. I... I may be more invested in this ongoing series than I ever have been in any other story. Once I found a good way to read it, I just could not stop (as evidenced by me finishing a book a got like 5 hours ago). The characters, the mechs, the sex, the fights, the drama and the fear of possible betrayal... I cannot properly express how it all just drilled into the center of my brain and set up a new home there.
I know NA2 only came out a couple months or so ago, and the third might not even be your next project, but I'll be waiting patiently for the next one. Definitely not going even a little bit insane in the meantime.
Definitely very sane. 🙃
