Every family has secrets and Natalie Morrigan was used to being kept in the dark. But when her childhood home is destroyed following the mysterious disappearance of her parents, Natalie soon discovers her secrets are darker than most. With no where else to turn, Natalie and her four lifelong friends seek out their estranged Uncle for guidance and he cannot wait to tell her the truth.

Her entire life has been a lie.

Genetically adapted with a power that will change the world, Natalie is hunted by Nautilus: an organization that claims it will use her power to achieve an everlasting peace. But if Natalie has learned anything, it’s that things aren’t always what they seem.

Question everything.

Nautilus is rising.
And Natalie's demons are coming to drown her.

Hope is an anchor, and Natalie Morrigan is drowning. Haunted by a power she can’t control, Natalie and her friends are determined to reunite their families and uncover the truth of their past. But with Leo missing in action and Uncle Chris out of the picture, Natalie is left harboring a mysterious key and a secret that isn’t hers to tell. Invited to masquerade as a Nautilus recruit, Natalie finds herself in the Helix: Nautilus’s center. Faced with old enemies and locked doors, she hopes to last long enough to find her parents. But Natalie isn’t the only one keeping secrets. With the fate of the world and her powers at stake, Natalie soon realizes the most dangerous demons she must conquer are her own.

Lest they drown her first.

All secrets must surface.

Natalie has found the worst kept secret in history. Now, to stay safe, all she has to do is keep her head down and obey the Regent.

But the cost of Natalie’s power is catching up with her. The past and present are a blur, Nautilus lurks at the city gates, safety is an illusion, and all around her reality cracks. While Edwin urges her to find an anchor and Leo strives to be her confidant, Natalie is convinced that to save herself, she must fix her family. And fixing her family means finding Brant.

Yet when a desperate move reveals one last puzzle from Christopher, Natalie uncovers the truth of her fate, of what the Coelacanth Project stood for – and facing it will cost her everything.

Regent is the final installment in the award-winning Coelacanth Project Trilogy. Every question will be answered, and all secrets must surface.
