Communication in international bargaining Book

I'm reading this right after Mustafa Akyol's "Islam Without Extremes" and this guy, while he does the valuable service of pointing out, as Akyol does, that neither side is blameless, is too quick to assert that things that Akyol argues are cultural are essential to Islam, while not part of christianity. If you're not a christian, I'd go with Akyol's book, which goes into more depth and doesn't have all the christian cheerleading this book does. He manages not to know that Mustafa Kemal and Kemal Ataturk were the same person, which makes me even more dubious of his scholarship. He also repeats himself too much.
