Blue paperback novel found near Michigan Street, South Bend

I found a blue paperback novel this afternoon around 2:15 pm outside the Century Center on Michigan Street in South Bend. It's a standard 6x9 inch mass-market paperback, with a creased cover and a spine that's a little cracked from use. The blue cover has white lettering and a subtle snowflake design, and a pink ribbon bookmark sticks out between pages around the middle. On the inside of the front cover there’s a small sticky note with the initials 'A.G.' that might help identify the owner. It looks well-loved but readable, and I’d hate for someone to be without it.
