Queens Of Osiris. The Severed Empire, #3

Ever since the demise of the Mountain King, Hermon Cordillera's daughters have stepped up and shared the throne as queens of the Osiris Realm. But when women go missing from the kingdom, they are unable to find whoever is responsible for the growing number of abductions. Meanwhile, Mykal - the young wizard - continues honing his magical skills with his mother, and his tactical training with Blodwyn, his oldest friend.
Living in secret within the ancient library ruins, they are surprised when a young woman shows up asking them for help. Tasked with unravelling the mystery, they soon realize clues are few and far between. Ill-prepared for the untold dangers that await them, they will need more than Mykal's magic this time in order to survive - and unravel the mystery of the people of Osiris who have gone missing.
