Blue paperback Nottingham travel guide

I lost my blue Lonely Planet Pocket Nottingham travel guide yesterday afternoon near Waterstones on Bridlesmith Gate in Nottingham city centre. It's a small paperback, about 4 by 7 inches, with a blue cover and a white skyline, in decent condition except for a coffee stain on the bottom edge and a dog-eared page. There's a tiny fox sticker on the back cover and a pencil note in the margin that says 'Route 11'. It really matters to me—it's sentimental and I need it back after using it on my visit to Old Market Square.
