Heart of Iron is Ashley Poston’s YA space opera duology. Heart of Iron (2018) draws on the Anastasia legend in a far-future setting, following a girl and her android companion. Soul of Stars (2019) concludes their story.
The first book sets up a galaxy ruled by an iron-fisted empire, with Ana and her android D09 on the run. The Anastasia retelling angle gives the story a built-in mystery about Ana’s true identity. Heart of Iron balances action sequences with the relationship between Ana and D09.
Soul of Stars (2019) raises the stakes for the conclusion. Ashley Poston went on to write romances like The Dead Romantics (2022), but Heart of Iron remains her only foray into YA science fiction. The duology format keeps the story compact, with no filler between the setup and the ending.
