Their first mission after the Calarni leads Yaden and Ivan to Goa, tracking down N'Bosoti artefacts. Encounters on the estate of Princess Kumari have implications both personal and political, but most importantly, lead to Yaiciz - right into the machinations of Princess Anya, Ivan's deranged sister.

Facing ancient monsters, an obstinate Vertex, a recalcitrant Duke and a traumatised Goddess, Yaden, Ivan and Colin will need all their courage and personal growth to save the day once again.

Written by award-winning authors Beryll and Osiris Brackhaus, 'The Two Princesses' is a riveting space-opera adventure novel about the difference between family and relatives, and the seventh book of the acclaimed 'Sir Yaden' series.
