I went into this blind so I didn't know what the book was about, its premise, nothing. And up until the I want to say maybe 30% to 40% mark I was kinda bored and considered dnfing it since I was so confused and felt like it dragged on. I decided to continue and I am glad I did because the ending really paid off. it got so engaging, suspenseful, thrilling and I was waiting to see what happened next.  

Read this if you love:
-True crime
-Book in a book trope
-Online sleuthing
-Twists

The main characters are well-developed and well thought out since I often find it hard to remember multiple characters or distinguish characters, but here I had no problem.
