'Before Adam and Callie were born, horrific plagues destroyed billions of people. Survivors built a new twenty-first century world, but now a fresh catastrophe threatens.
'Callie and Adam, once unquestioned members of the elite class, now find that they must strive to protect the very society that rejects them as fabricants - manufactured genetic beings.
'They embark upon a perilous journey that will pit them against the scientist who created them in a laboratory - and who now threatens to unleash dreadful weapons to achieve ultimate power.'
