The Blood Gift
NE Davenport, 18 April 2023
The final book in The Blood Gift duology, The Blood Gift sees elite warrior Ikenna hunted for the blood gift she’d paid to save her squad. And not just by her own people, the Blood Emperor’s Warlord is now also hot on her trail. Problem is both these realms are also waging a bloody war against each other, and she and her crew are smack-bang in the middle of it. No one realises the extent of the incredible powers the Goddess of Blood Rites gave her, though – or that it is slowly tearing her apart from the inside. Perhaps she can put it to some good use though… in The Blood Gift.
