Beneath the ice of Jupiter's moon Europa lies a secret: Atlantis didn't sink—it fled. Now the ten adopted MacIver siblings must help this ancient civilization escape before Earth's exploration vessels arrive. But not everyone wants change.

When Brad discovers his genetic connection to Atlantean leadership, he finds both love and danger. As he grows closer to Iris, a young woman challenging her society's traditions, his brother Allen uncovers darker truths. The city's radiation-damaged engines aren't the only threat—prejudice and oppression run deep.

With time running out, the MacIvers must navigate political intrigue, rescue an abused daughter of power, and find a way to transform a rigid society. But the hardest challenge might be the price of success: are they willing to separate a newfound love to save a civilization?

Some secrets are worth keeping. Others must be exposed, no matter the cost.
