Red-spined paperback sci-fi novel found near campus bookstore

I found a red-spined paperback sci-fi novel this afternoon around 3:15 pm outside the Barnes & Noble on University Drive in College Station. It's a well-loved copy, with a coffee stain on the back cover and a torn corner. Inside, a handwritten bookmark reads 'A. Patel' and there's a small red sticky note tucked in with 'CS101' written on it. It seems to have been shuffled around campus lately—maybe from a late study session to the library. If this is yours, drop me a note here with identifying details so we can get it back to you; it seems meaningful to the owner.
