This is a really fun book. The concept and the execution are innovative and interesting. The text is set up in the form of slack conversations, so there's little description other than that given by context clues. This made for a very fast-paced read, I finished this whole book in just ~2hours, where a book of this many pages would usually take me ~5hours to read.

However, I am rating it 3.5 stars as although I had fun reading it, the short format meant a lot of the character and plot development was mostly surface level and I was left with too many questions unanswered by the end. One unanswered question seemed to me to be the whole point of the book and so I was a left a bit confused and underwhelmed.

Overall though, I highly commend the author for the ingenuity it required to write this book, however I just wanted a bit more from the content.
