A bit of help needed?

I don’t know if this is the right place to ask but I need some help. I took a book out of the library and it’s about trans stuff, it’s really obvious it’s about it. The problem is my mom is very very transphobic and homophobic. Meaning if she finds out I’ll be in a lot of trouble. I need some advice of how to sneak the book away?? Any and all suggestions are greatly appreciated, I just want this to be done with.

Additional info: The book is late due and I had to use my mom’s library card because I lost mine. I know it was a stupid STUPID mistake but I was desperate. I know I’m stupid for doing it.
