Red paperback mystery with blue bookmark found near library

I found a red paperback mystery with a blue bookmark this afternoon, around 3:15pm, outside the Allentown Central Library on Hamilton Street in Lehigh Valley. The cover is glossy red, the book is about 320 pages, and there's a light crease along the spine from wear. On the back cover is a small green sticker that reads 'Maia,' and a cat-shaped bookmark is tucked between pages near chapter 12. The book looks well-loved but in good reading condition. If you recognize it, I’d be happy to reunite it with the owner.
