I got my signed copy (it’s the cover with Isom and Yaira) a couple of weeks ago, but also didn’t want to open it, so I just ordered a regular copy of the book, there was only one cover left. Got that and read it yesterday.
It’s a good origin, it’s not really long enough to go very deep into character and history of anyone, just hints at things. The dialogue is a little awkward in places, some words I wouldn’t use here and there, but that’s probably my only criticism. I like what it’s setting up, and I’m really looking forward to following this universe as it expands. Happy to have gotten in on the ground floor!
