Their love is written in blood.
Hannah and Scott return to Thunder City, their love stronger than ever. The Oversight Committee has other ideas, and decides the two alternative humans must be separated because they are too dangerous together.
Refusing to comply, Hannah and Scott go on the run again. For Hannah, help comes from a sympathetic doctor who understands her ability to heal and promises to protect her from the Committee. Scott discovers his own mentor, who uses live ammunition and a take-no-prisoners attitude with Scott's translocation power.
Both of them flourish under their new trainers, until Hannah asks Scott to investigate a young boy with mysterious surgical scars. Scott's mentor tells him to ignore the request, that preparing for the coming war with the Court of Blood is more important than the life of one insignificant boy.
Scott fears he's losing Hannah to her mentor and a medical mystery — and worse, that's he's losing his own humanity to fight a ruthless enemy.
Hannah and Scott are rebels in a city that prizes law and order. They rescued each other from Star Haven's nightmare quarry prison, but can they save each other from a tangled web of intrigue while the Court of Blood pulls the threads tighter?
