Book 1 of the Fire Sermon trilogy

Born as twins
Raised as enemies
Bound by death
Since the blast that reshaped the earth, only twins are born. The one deemed imperfect is branded at birth and sent away. Twins share nothing but the moment of their death: when one dies, so does the other.
But Cass and her twin, Zach, cannot be separated.
In this scorched and broken world, Cass’s bond with her brother may be the most dangerous thing of all.

The trilogy was shortlisted for the 2018 Sara Douglass Book Series Award for best SFF book series.
This book is a thought-provoking whirlwind of a story, with a fab lead character, grisly politics and brave adventure. I loved it!
