Anyone with a serious reading habit can tell you: When it comes to deciding what book to read next, sometimes it’s all about the mood you’re in.
 
In fact, many of us even have multiple books going at once, just to facilitate this phenomenon. Some days you want to cry. Some days you need to laugh. You may want to revisit old stories, or check out the new book that everyone is talking about. Then there are the days in which you’re in the mood for something totally random. Wolves, say.
 
With summer reading season upon us, we’re here to help. We’ve gathered here 15 different themed collections, each dedicated to a particular mood, topic, or circumstance that you might want to read about in the coming months. Most of the titles we've included are relatively recent, but we’ve peppered in some older classics where the fit is just too perfect to ignore. As always, hover over the book covers to learn more.
 
Feel free to add in additional suggestions in the comments section. Also, we’re curious: When it comes to recreational reading, do you tend to concentrate on one book at a time, or do you sometimes have several books going at once? Make your case below, play nice, and add anything interesting you find here to your Want to Read shelf.
 
Mood reading. It's a bookworm thing.
