I'm Bugg'in

Eve checked out this book from the library and I had this weird hesitation when she got it and that normally never happens. Well it's been a good couple weeks and we had the book all stacked up to go back by the stairs and I forgot to take them. I came home Monday night after work and they were not in the stack anymore...I cannot find one anywhere and it is driving me BONKERS!! I do not understand how a large book can simply disappear????? What's up with that? I am so frustrated I called the school to see if she turned it in there and no luck! I am at a loss, I know it's just a book, but SERIOUSLY....where the heck is it.
