Well, Bioware have responded to the outcry: “The teams at Del Rey and BioWare would like to extend our sincerest apologies to the Mass Effect fans for any errors and oversights made in the recent novel Mass Effect: Deception. We are currently working on a number of changes that will appear in future editions of the novel. We would like to thank all Mass Effect fans for their passion and dedication to this ever-growing world, and assure them that we are listening and taking this matter very seriously.”
Thanks to IGN for the info.
