Discrete Mathematics, Mathematical Reasoning and Proof with Puzzles, Patterns, and Games by Douglas E. Ensley and J. Winston Crawley, hard cover edition. The hard cover does have some decent wear, but the pages are in great condition. There is a tiny bit of writing in the book; I only seen writing on a few pages towards the beggining of the book. The writing is in pencil, so it can be erased if needed.
