The second son.
Lieutenant Commander Jace Harrow is the second son of House Morningstar—the spare, not the heir. Armored with an arrogant mask, Jace keeps the world at arm's length to protect those around him from becoming targets for his bloodthirsty brother.
The broken sword.
Lieutenant Bryn Viera was a shadow sword and a decorated officer, dedicated to protecting her people. But for the past five years she has lived as a slave and has the scars to prove it. Bryn vowed to escape or die trying—until she met Sabine.
The slave.
Born into slavery, Sabine never expected to fall in love. Her feelings for Bryn sparked her desire for a new life, but now Sabine is in phase, consumed by the need to mate with a male. Her dream of freedom with Bryn is on the brink of destruction, for to deny the phase means death.
Thrown together by the unforgiving demands of the phase, they must unite to save Cyprena's people from a deadly new bioweapon—or be destroyed by the scars of their pasts.
