Stupid library

I am loving my library card. It means free access to a large range of books both for myself and for M and it's located in a very handy spot just next to the train station and it's great.
BUT! There is an obvious problem with libraries; one I was bitterly reminded of today: other people go to the library too. And sometimes one of those other people will want to read the same book as you.
I am almost finished with "The Way of Shadows" and before swim school M and I ducked into the library to pick up the next book in the Night Angel Trilogy. It was there a few days ago when I got the first book out. IT WAS NOT THERE NOW!
I seriously was on the verge of crying in hysterics. NOOOOOOOOOOOOOO! How distressful, how awful, how evil of that other person. Why did he/she need to read that particular book right now? It's such a crappy thing to do to me. Sniffle sniffle.
What if he/she is a really slow reader and ends up taking 3 weeks to finish it? I can't handle that, I just can't!
Panic!!!
Otherwise it's been a good day... tomorrow is going to be insane.
