I'm surprised no one has mentioned this yet. The Official Star Trek site added a new intetview with Christopher Bennett. In it he discusses The Struggle Within, and a little bit about Only Superhuman, and Forgotten History.
Christopher, when you said it was a sequel/prequel to Ex Machina, did you mean it actually follows up on elements of EM, or does it just take place (partially) in the same era?

This is a Sol System where transhuman enhancement has put considerable power in the hands of many individuals, and a lot of them use that power harmfully, but others have dedicated themselves to helping and protecting. A lot of the book's thematic thrust is examining the responsibilities, limits, and abuses of power over others, whether it's physical, political, emotional, or sexual power.
