When we were last at the library, Eldest was trying to find books on one of her current great interests, herbology. Unable to find much beyond gardening books, she asked a librarian. After searching for a while, the librarian recommended a book and put an order in, since it wasn't at our branch.
A few days later, Eldest picks up the book and gets...
The Dictionairy of Sacred and Magical Plants.
Turns out it's all about the rituals and such surrounding plants.
Not sure what the librarian thought she was looking for, but this ain't it!
