A Page Angel is when you hunt for a page like a maniac, and the book gives it to you like it was your best friend.

I tore through my book like a madman and it gave me the right page. That book is my best friend.

I flipped through my novel like I was searching for a lost dog, and it gave me the right page. That book is a good friend.

I was looking for the exact paragraph I needed and the book handed it to me. That book is a traitor.
