Per the author info page at the end of the book, this is Kali Wallace’s first non-YA book, but it still has the distinct feel of a YA book, something I started to notice about 2/3 of the way through, then I got to the afore mentioned info page and said “ah, right, that makes sense then”. That’s not to say this isn’t a great story, some of our favorite modern stories have been YA or adapted from YA I’m a huge fan of post-apocalyptic stories, especially ones that happen fairly far in the future. In the “Salvation Day” universe, humanity has been able to send generation ships out to the stars, started mining astroids, and had a generally advanced stage of technology. There was a massive collapse however, and humanity struggled to save society from itself, and it was only after a long period of rebuilding and restructuring that we were able to look to the heaven again. It’s the struggle between those two ages that the dominos are set up for this great story. Kali Wallace is new to me, but I’m going to keep an eye out for new books from her, this one was worth my time reading it, and I’m hoping to see more science fiction from her.
