The Promise. The Drath Series, #25

A Lazy Vacation. That's all that Narcisse had planned. Just a long, lazy vacation on a light-grav world with her little sister Tracey who absolutely claimed all credit for choosing the lovely tropical location. And really, she deserved credit. The islands were gorgeous. And filled with danger. A quiet dinner turns into running for her life as Narcisse meets her first alien. With the Drathanni Shanni sick, her bodyguards abandoning her, and threats coming at them from land, air and sea, Narcisse makes a promise to get Shanni to safety.
Even if it starts a galactic war. The Promise by Meyari McFarland is a fast-paced space opera thriller that will keep you on the edge of your seat to the very last word.
