Galena Margolis, a brilliant scientist with a tragic past, is determined to fulfill her destiny and develop the vaccine that could save millions. Yet when Galena's test subjects meet with foul play, it's clear that someone is still determined to stop her, and that Galena herself is a target. As the Ferry empire forges a plan to keep her safe, Declan Ferry, the politics-hating black sheep of the family, steps forward to protect her--but the emotional cost may be more than either of them is willing to pay.

As unknown enemies close in, it becomes terrifyingly clear that they threaten to destroy not only Galena's lifesaving work but also the very fabric of fate. As Galena and Declan race to uncover the traitor, they also forge a special bond that could save both Galena and those she's sworn to help. Torn apart by the past and hunted by those she trusted, can Galena find room amidst her fears for a passion that could make her stronger than ever? And even if she and Declan can find their way together, will it be enough to keep the future from coming apart at the seams?
