Paperback novel found near Ithaca Commons; red maple bookmark

I found a paperback novel this afternoon around 3:15pm outside the Ithaca Commons on State Street, near the State Theatre. It's a teal-covered mass-market paperback, about 350 pages, with a bright red maple-leaf bookmark sticking out between chapters and a small coffee ring on the back. The inside front cover has a handwritten note that reads 'A. Chen.' It seems well loved, and if the owner sees this, I hope they know someone picked it up to help reunite it.
