Penguin Classics edition of To Kill a Mockingbird, blue

I lost my blue Penguin Classics paperback edition of 'To Kill a Mockingbird' yesterday around 3pm near the Barnes & Noble at MacArthur Center on Granby Street in Norfolk, in the Hampton Roads area. It's a 320-page book, soft cover, with a slightly creased spine and a small coffee stain on the back cover. Inside I've left a blue ribbon bookmark that's frayed at the end, and there's a pencil note on page 120 about a class reading. It means a lot to me; it was a gift from my aunt, and it's really the first book I reach for when I need comfort. If you found it, please let me know; I really need it back.
