Light-blue paperback with cherry blossom cover

I lost my light-blue paperback edition of 'City Trails' yesterday around 3pm near the Peace Gardens, outside the Millennium Gallery on the Moor in Sheffield city centre. It's a 320-page book with a slightly creased spine, a coffee stain on the back cover, and a small pencil sketch of a cat on the first page. There's also a thin, mismatched bookmark made from a cafe receipt tucked between pages. It has sentimental value; I used it as a gift to myself after moving here, and I really need it back.
