Review

I always recommend listening to the audiobooks of The First Sister series. And The Last Hero is no exception. This multiple perspective novel with multiple narrators is unparalleled. The Last Hero is this series finale to this epic and underrated science fiction saga. It’s multi-layered as it discusses choices, family, and revolution. There are so many rich character developments by this series finale that takes this zoomed out approach to examine the hope of humanity, of fixing our mistakes, and taking responsibility. Just when we thought the stakes and the danger couldn’t get higher, The Last Hero bursts onto the scene.
We examine what loss, tragedy, and these choices with rippling consequences, can do to us. What it turns us into. We can become heroes, martyrs, victims, and villains. I was expecting this reaching story about choices and consequences, bloodshed and betrayal. But what I wasn’t expecting was a story with hope. There’s this flickering flame of hope, of possibility amongst these ashes. By this point, I was attached to every character and their arcs are solidified into such rich stories.
