The Chalice of Malvron - Argetallam Saga, #3

Janir Caersynn Argetallam wakes in Adasha with little memory and no certainty of what is real. The Argetallams around her claim to be family, yet feel like strangers. But with war approaching, she fears questioning her loyalties. When the Argetallams bring an arcane artifact into the war against the Brevians, Janir stands with them despite her reservations. Only when she meets Saoven and Karile, two spies for the Brevians, does it become clear her past holds secrets far more dangerous than she imagined.
With invasion imminent and mere days to choose, the time comes to take a side. Faced with two versions of the truth, she must either betray the family she has come to love or a homeland she can't remember.
