Blue hardcover poetry book with gold spine

I lost my blue hardcover poetry book yesterday around 3pm near the Harold Washington Library Center on State Street. It's a compact 256-page volume with a gold foil title on the spine and a red satin ribbon bookmark peeking out. The cover is slightly worn, the corners nicked, and there's a faint coffee ring on the back from a morning at Millennium Park. It has sentimental value—it was a gift from my late aunt and I really need it back.
