Found paperback book near Allen County Public Library

Found a paperback book this afternoon around 2:15 pm on the sidewalk outside the Allen County Public Library on West Berry Street, Fort Wayne. It's a mass-market edition of 'Where the Crawdads Sing' with a teal-blue cover; the spine is creased and there's a faint coffee ring on the back. Inside the front cover is a Fort Wayne Book Club sticker and a yellow sticky note with the name 'M. Rivera' and a partially written phone number. I'd really like to help get it back to its owner.
