Elsewhere's Twin: a novel of sex, doppelgangers, and the Collective Id

Prophecies don't end with happily ever after. Fin and Rook never wanted to be heroes in the first place, so it's no wonder they did a sloppy job of it. All the same, they thought they'd earned a bit of downtime by averting the enslavement of the entire human race. And, Willow's return should be the best news imaginable. But it's hard to fit the pieces back together without cutting yourself on the edges. It would be easier with fewer distractions. The alien spiders have discovered the prophecy, and disapprove of the reluctance of those called upon to fulfill it. Rook's demonic inner children remain at large in her mind, with ambitions. Meanwhile, a new adept takes instruction in the attic of Threshold House, offering Severin another chance to assault the Collective Id, while the nanotech body jewelry falls into yet more wrong hands. Every player is trying to upend the board. To learn the true nature of this shifting game of shadow-selves, Rook and Fin traverse hellish mindscapes and duel bizarre new adversaries alongside familiar ones. Every answer leads to new questions, with the fate of the world hanging as the ultimate riddle. But Rook and Fin are driven by something far more important.
