Rachael Sparks was born in Waco, Texas. She graduated with a degree in microbiology from Texas A&M University and her first college job was ghostwriting a nonfiction science book. After a decade-long career in Austin, Texas, as a transplant specialist, she joined a startup fighting healthcare acquired infections. After relocating with her husband, young daughter, and mother to Asheville, North Carolina, she finally put her first novel onto the page. In her free time she serves on the board of the Asheville Museum of Science and loves to cook, brew, garden, and spend time with friends and family in between obsessively researching new science concepts, history, or new recipes.
In the final battle with drug-resistant bacteria, one woman's blood holds a secret weapon. Rory and her father have survived the antibiotic crisis that has killed millions, including Rory's mother--but ingenuity and perseverance aren't their only advantages. When a stoic and scarred young military veteran enters their quiet life, Rory is drawn to him against her better judgment . . . until he exposes the secrets her mother and father kept from her, including the fact that her own blood may hold the cure the world needs, and she is the target of groups fighting to reach it first. When the government comes after Rory, aiming to use her for a cure it can sell to the highest bidder, she's forced to flee with her father and their new protector. But can she find the new path of human evolution before the government finds her?
