Blue paperback novel with cat sticker

I lost my blue paperback novel yesterday around 3pm somewhere near the Springfield Public Library steps by the Main Street entrance. It's a softcover edition of The River Between with a white title on the cover, a worn spine, and a small dog-eared corner. Inside the front cover there's a little hand-drawn blue cat sticker and a purple ribbon bookmark that sticks out a bit. The book mattered to me—it's a gift from my mom—and I really need it back; it has sentimental value.
