"The year is 1902, and the world is changing with the new century. Twenty-one-year-old Ava Stanley, the daughter of two celebrated Arcane Taxonomists, has much to live up to--however scarce her magical abilities may be. While her parents draw power from spectacular birds and megafauna, Ava's connection to the natural world is much smaller, stemming from the microscopic. This is useful in her quest to become a doctor, as she studies the burgeoning links between bacteria and disease, but it means Ava's power itself is also smaller. Even so, she plans to make the most of it when she boards a ship to Nassau, where she'll continue her research. But those plans change when pirates take over the ship, bringing with them danger, mystery, and the stirrings of war. Amid the chaos, Ava forges connections with her fellow travelers. And in them, she begins to find that every tiny piece of the world has the power to strengthen it...or shatter it completely"--Back cover.
