Red paperback mystery with leaf bookmark

I was at Lancaster Central Market on North Market Street yesterday around 3pm when my red paperback mystery vanished from my tote. It's a paperback edition of 'The Lantern Night' with a red cover, slightly worn corners, and a green leaf-shaped ribbon bookmark sticking out of page 142. The spine is creased and the back cover has a small coffee stain. It has sentimental value because it was a gift from my grandmother who passed away last year. If you found it, I’d really appreciate hearing from you—my email is below and I’m hoping to get it back soon.
