"Evan struggles with being different, having the complete memories of two other people who lived sequentially before him. He believes he is unique until he meets Poppy. She is like him, except that she is much older, remembering seven consecutive lives. But there is something else: she is a member of the secretive Cognomina. They are, in effect, immortals, compiling experiences and skills over lifetimes into near-superhuman abilities that they have used to drive history over centuries"--Publisher's description.
