Blue paperback poetry collection with yellowed edges

I’m missing a blue paperback poetry collection, pocket-sized, about 5 by 8 inches, with a blue cover and a yellowed spine—Penguin Classics edition. It has a tiny coffee stain on the back, and a red ribbon bookmark peeking out from page 92; the pages are dog-eared from lots of reading. I last had it yesterday around 3pm near the Yakima Public Library on 3rd Street by the bus stop outside the coffee shop. It was a gift from my grandmother and feels really sentimental; I’d be grateful to get it back—reach me at [email protected].
