When you realize that your favourite author just released a new book and you can't go get it. Literally i hate it when I'm to busy to pick up a book at the store. Some of you might be like, "Why don't you go get it at the public library?". Well because, usually when a book is released the library won't have a copy for a while and when they do, you get put on a list of thousands of people who want to read it. But sometimes it's worth the wait. For example, while I furiously read through The Lost Hero (which i do own) i had to wait weeks before i had my hands on the next book, since i didn't own the rest of the series. By the time i got the next book, i forgot about somethings that took place in the previous book. But it made me read like crazy when i had the second, third, fourth and fifth.
