In theory, all aspects of this book seem perfect. In reality, the execution is what ruined those elements for me.

The writing tries to mimick the feeling of a nonfiction memoir or documentary. This is successfully done until the actions started to get unrealistic. If you want your book to feel like a documentary, you can't let your characters get away with unrealistic shit. 

Cate drove away for like 1½h and you're gonna tell me no one found her? She was like a town away.

Additionally, because of this very prominent style of writing, it was impossible to connect to any characters, even the MC. They were vessel's retelling the story instead of real characters. Not once did they feel like real people. Therefore, I also couldn't bring myself to care about any of the emotional drama going on.

While I was interested in the story and the complexity of the mess unraveling, I didn't enjoy this nearly as much as I had hoped to. Part of that definitely is also because Cate Kay is just a very unlikable character and I found myself not rooting for her. Instead I got frustrated with the fact that no one in the book actually seems to care that she's a selfish bitch who makes a lot of very egotistical mistakes repeatedly and doesn't seem to learn from them. She did not deserve Amanda.

However, this was a quick, entertaining read and I do see the appeal. As said, the idea of the story appealed to me and kept me reading. The multi media used in here was a nice idea and made it feel like a rela documentary. However, honestly, I hated the inserts of her book in here. Simply because it was so horrendously written. 
Fun idea, meh execution.
