The Dispossession of Dylan Knox

While coordinating a tour event for her boss, the secretary general of the UN, Brooke Chappelle encounters her high school sweetheart Dylan Knox but Dylan doesn't remember her. In a public confrontation with the secretary general, Dylan nearly costs Brooke her job. Determined to unmask what she believes to be an impostor, Brooke spends a weekend with Dylan and witnesses some extreme personality changes.
He claims there are actually three minds inhabiting his body, but his explanation is impossible for Brooke to believe. Dylan works for a private space company on a project to beam solar energy from orbit and Brooke fears he might have sabotage in mind. As their relationship deepens, her own feelings start to betray her. She might be forced to report Dylan to her nation's security agencies-falling in love is the last thing she needs.
Especially when Dylan tells her that the very future of the world for the coming century may depend on the choices she makes.
