A secret biotech project. A stolen logbook of covert scientific data. A baby with a genetic code that could save the future of humanity.
A female teen at the center forced to make a choice.
Sienna Yardley thought she had survived the worst—The Eden Project, a deadly virus, and a dangerous biotech conspiracy.
Now, just when life seems ready to settle down, her baby brother Noah is born.
But Noah is different. And Sienna soon realizes that the secrets surrounding his birth may be connected to the most dangerous players in the biotech world.
As hidden agendas, stolen research, and unanswered questions begin to surface, Sienna is pulled back into a world she thought she'd escaped.
She begins to question those she once trusted. Seemingly unsurmountable obstacles keep facing Sienna and her friends. Corporate greed, family agendas run deep. How far are the Giann’s willing to go for revenge and control of the future?
To protect her family, she must uncover the truth behind Noah—and a mysterious file known only as the XF Profile.
Because some secrets are too dangerous to stay hidden.
And some futures are worth fighting for.

October 28, 2026A biotech thriller with a lead female character faced with unimabinable decisions keeps the reader engaged. Sienna struggles with family loyalty, love, and her ambition to be independent. Writing the 3rd book in The Sienna Yardley Series kept me on the edge of my chair, leaning into Sienna's wants and hurts every step of the way. Does she stay true to her mission and values without losing herself? Read this page-turner to find out! (Catch up on Sienna's journey by reading The Eden Project and The Crescent File, you won't regret it!)
