A thick, smoothly laminated paperback textbook titled "The Chemistry and Physics of an Abundance of Highly and Moderately Radioactive Substances Volume II". The pages appear to be used but in good condition. Almost all of the pages contain highlighted areas, arrows and scribbled notes made with a blue ballpoint pen. Sticky notes of all colors are similarly written on and distributed throughout the book. The book is filled with small text and frequent diagrams, often in color. Inside the front page is a scribbled note, reading, "I've used this book enough- maybe you should read it now. I look forward to working with you. Merry Christmas from your assistant, Fatima."
