DNF @ about 120 pages in. Don't even care to try getting more into it. 
 I had such high hopes for this book because the gorgeous cover, the amount of people who have it on their TBR, and the booktube hype of it. I guess that's all it was though hyped. Even the summary sounded pretty intriguing and attention grabbing. Something different from all other YA books and one of a kind is what I was hoping for. What I got was NONE of that. 
 The Characters Aza and Jason are our two main characters. Aza has the worst personality imaginable and the first few chapters were her talking about how she pushes everyone away because she's destined to die due to this unknown illness. It got old and annoying real fast. I never really grew or felt connected to our main character but instead she just got on my nerves and seemed so pessimistic. Then there's Jason who is this pessimistic main characters best-friend. He had some good traits such as all he wants really is to see Aza happy but that's about all I got from him. I know how most YA books our heroine is supposed to start out typically weak and have this "coming" of strength type story but I wasn't feeling it. 
 The Bird People.....Just...No. What the fuck. I was so lost and confused by the whole premise. The book just lacked SO much explanation. One minute she's dying in an ambulance then the next minute she's on a ship in the sky. What?! It was just too weird. 
 Plus the writing style wasn't my cup of tea either. The character spoke in a very sarcastic and witty tone which I couldn't get into.
