Yup, 3 days for me too. By chapt. 3 I was mentally out but couldn't put it down. I never bothered with ISCF. The Mexico Malawi issue was enough to convince me that there was NO Holy Spirit operating on this organization therefore, doctrines were irrelevant. Instead, went straight to Steven Hassen.
If only I would have given myself permission to read COC when it first came out! Better late than never, though.
