This book started slow and I was leaning more towards 3-4 stars and then the second pov came and flipped my perspective and grabbed me by the throat and I'm still emotionally distraught. 5 stars.

Edit: Reread a year later.
This book is still phenomenal, and I think almost better on a reread because you know what's going on.

Definitely don't look up spoilers, but otherwise the first time you read all of Julie's notes it can be kind of slow until you get to the Kittyhawk section and all the pieces come together.

But on a reread it hits you even more because you KNOW exactly what's going on, and even worse, how it ends.

Kiss me, Hardy! Kiss me QUICK!
