"Destiny Disrupted" is pertinent to RLST 2600 because it focuses on the history of the Muslim world and highlights how western society and religion was, and is, perceived by the eyes of Islamic culture. Ansary answers many questions about why such huge friction exists between Judaism, Christianity, and Islam, but even he cannot answer them all.
I would highly recommend this book to anyone who has the least bit of interest in history, but
