Blue Penguin Classics Pride and Prejudice edition

I'm hoping someone picked it up by mistake. I'm missing my blue Penguin Classics edition of Pride and Prejudice, a gift from my grandmother. I left it yesterday around 3pm near the Burton Barr Library at 1221 N Central Ave, Phoenix, by the cafe outside on the plaza. It's a lightweight paperback with a slightly worn blue cover, about the size of a standard novel. Inside, there's a handwritten note with my initials P.K. on the flyleaf and a small coffee mark along the bottom edge. It has sentimental value to me, and I'd be incredibly grateful to get it back.
