The amount of swearing is insane and feels really unnecessary. Oli's inner monologue feels like a mix of "kill me" and "f*ck me" and its gets a bit repetitive and annoying.

No idea what's happening the first half of the book and it took a lot of willpower not to dnf, but the action took off around the last 45 minutes of the (audio)book. 

Does it sound like I hated the book? Yes. Did I? No. And I actually will read/listen to the other books because I'm sure it will get better lol.
