The exciting conclusion to a sumptuous gaslamp fantasy series Leanna Renee Hieber brings Victorian London and New York to life and fills both cities with ghosts and monsters. Two groups of paranormally talented investigators discover that the Eterna compound—thought to be the key to immortality—is, instead, a powerful protective charm. That protection is sorely needed, for both England and the U.S. are under attack by dark forces. Having vanquished the demonic pretender to the British throne, the now-united forces of the Eterna Commission and the Omega Department reach America ready to take on a new menace. But like the United States itself, this evil is rapidly spreading from sea to shining sea. Will the new magic our heroes have discovered be strong enough to defeat it? With its blend of Victorian details, complex plots, and compelling characters, Hieber's fascinating historical fantasy continues to earn critical acclaim and has a dedicated readership.
