Dog-eared paperback novel with blue bookmark

I lost my dog-eared paperback novel yesterday around 3pm behind the Roseburg Public Library on Oak Street. It's a paperback edition of The Night Circus by Erin Morgenstern, with a blue ribbon bookmark that has a tiny brass key charm. The back cover has a small green sticker that says 'Best Reads'. The cover is soft grey with a subtle starry motif and a light coffee stain along the bottom edge; the pages are well-worn from years of late-night reading. It was a gift from my grandmother, so it has sentimental value and I’d really appreciate getting it back.
