This is how you commit to the bit on interestingly formatted books! This is so incredibly well done, and brilliantly thought through - an example of when the substance is as strong as the style, which is so often not the case with interestingly formatted books.

Personally, I do love an interestingly formatted epistolary and this delivered! The formats (tweets, blogs, reddit, etc) all fit well together and make sense in the narrative. The only thing I wasn't so keen on was a quirk in the actual layout - it tripped me up in places where the next epistle started right at the bottom of a page rather than on a fresh page but it's a small quibble.

I really enjoyed the story itself, a few interesting twists and turns that kept it fresh and interesting to the end. And, rather skillfully, the characters feel well crafted and you can get to know them which can be difficult with this sort of format.

The only thing I was unsure about was the habit of replacing the names of things - deep web instead of dark web, but also the movies Riley reviews are all fake names alluding to real movies. At first, I thought was fun, but then I started to find it odd as to why it was being done this way, and wondered if it was then part of the plot - is this an alternate reality, etc. In the end, it didn't seem to be for any particular reason and the more I thought about it the more it irked me as other things weren't changed - like websites (twitter, reddit, AO3, etc). That said, it didn't bother me so much as to ruin my enjoyment, it just made me ponder why it was done this way and perhaps whether I missed something in the plot that explained it.

Overall I enjoyed this immensely and have to give massive kudos to Cat for such a brilliantly crafted volume.
