Blue Penguin Classics poetry book, gift from grandma

I lost my blue Penguin Classics poetry book yesterday around 5pm near the Starbucks on Clematis Street in West Palm Beach, Palm Beach County. It's a small hardcover, about 6 by 9 inches, with a blue cover and white lettering, and a yellow ribbon bookmark. The spine has a tiny gold dolphin sticker, and there's a pressed lavender flower tucked inside between pages. The edges are a little worn, with a faint coffee stain on the back cover. It was a gift from my grandmother and has huge sentimental value; I really need it back. If you found it, I’d be grateful to get it back—email me at [email protected].
