Will I have to replace this library book?

Today I checked out a book at my local library and when I bent down to set down my nachos, the library book fell into the hot sauce I had on the nachos and my other books I had in my hands fell onto the floor. I looked at the extent of the damage and the hot sauce is on the tips of the pages inside the book and when you close the book, there is this big noticeable stain on the pages. Will I have to replace this book? It's looks like I will have to.
