I know you’re asking where to buy it, but I’d actually recommend getting 'Glory' through a library app first if you can, especially if you’re unsure about committing money. The premise sounded interesting to me too, but I found the execution a little flat—it’s one of those books that gets a lot of hype in certain circles but might not land for everyone. The online retailers are pretty straightforward: Amazon, Barnes & Noble, Bookshop.org for supporting indie stores, Google Play Books, Apple Books, you know the drill.
I bought my copy on Kindle because I was impatient, but the formatting had some weird glitches on my older Paperwhite, paragraphs bleeding together in a couple spots. It wasn’t a deal-breaker, but for the price, it was annoying. Maybe check the sample first if you go digital. I’ve seen physical copies at Target occasionally, but their online stock is hit or miss.
Honestly, the search for where to buy it led me down a rabbit hole about the author’s other work, which I ended up enjoying more. Sometimes the hunt for the book is more fun than the read itself, but that’s just me. My copy is just sitting on the shelf now, looking pretty but mostly unremembered.
