Invisible Sun — S.J. Davis

In Victorian London, at the beginning of the Industrial Age and the height of man's obsession with alchemy, scientists give birth to the foundation of modern genetic science. As steampunk airships cut across the foggy city of Gravesend, vampires are accidentally brought to life. But instead of scavengers prowling the fringe of society, these creatures quickly evolved to be the respected organizers of the Society, a universal religion, and the Guardians of Science. Unfortunately, one stray drop has spilled from the vein. Draegan, heralded from birth as the genetically perfect vampire, has turned rogue, attacking the women of London's East End. Only his brother, with the help of Lady Astrid West, can hunt him down before he is able to unleash his full insanity upon the helpless city. And only another birth, the secret birth of a forbidden vampire, can stop his madness. Vampires! Romance! Steampunk!
