Hardcover 'The Night Circus' found outside Prescott Public Library

I found a hardcover copy of The Night Circus this afternoon around 2:15pm on the sidewalk in front of the Prescott Public Library on Cortez Street. It's a well-loved book, with a blue cloth cover and a red satin bookmark peeking out from page 199, plus a small coffee stain on the edge of page 214. Inside the cover there's a pencil inscription that says 'M. Chen's book'—a little clue that seems kind of unique. If this rings a bell, maybe the owner can share a favorite passage or the exact bookmark used; I’d really like to help get it back to you.
