Sci-fi a fantasy

Leigh grew up in Rotterdam, drawn to the waterfront as an escape from her unhappy home life. Enchanted by the undersea world of her childhood, she excels in marine biology, travelling the globe to study ancient organisms.  

When a trench is discovered in the Atlantic Ocean, Leigh joins the exploration team, hoping to find evidence of Earth’s first life forms. What she instead finds calls into question everything we know about our own beginnings, and leaves her facing an impossible choice: to remain with her family, or to embark on a journey across the breadth of the cosmos.
