Checking out a book, dont want my mom to find out what it is about?

How can I check out a book from the library if I dont want my mom to know what it is about? I want to check out the book Perfect by Natasha Friend and it is a book about a girl with an eating disorder and I have and eating disorder so I dont want my mom to know what it is about becuase it may raise her suspisions, but if I say I want to put that book on hold at the library, she will ask what it is about.
