This book is on Luke’s book shelf. Forty Days is a 1992 non-fiction book by Bob Simon, an award-winning veteran journalist for CBS News. The book describes the forty days he spent being imprisoned and tortured by the Iraqis after being captured, along with four of his crew, during the Persian Gulf War in 1991.
It’s not clear whether Luke or Jess is reading the book – but like Lorelai and Rory, there is a good chance that they share books anyway. If it’s Luke’s book, it shows that, like Jess, he has an interest in journalism. (It feels as if everyone is interested in journalism on Gilmore Girls!).
