Earth has been destitute for 1500 years, and the first remaining humans have just returned to find that Earth isn't deserted as everyone believes. The Nagas traded the first humans back alien tech for females. The females run and are caught to start this adventure. The first two books in this box set run semi-parallel to each other, and the third continues on with their underlying story arc. The three books get progressively darker as well.
Gemma is the head communications officer, and she can't believe she is being turned over to snake-men for unknown tech. She runs but is caught by a viper. Gemma and Vruksha learn how to trust each other.
Daisy has never been loved or cared for by another, and she is now stuck being a pilot on the return trip to Earth. When she runs, she is first caught and kills her captor, only to be taken by a king cobra. Zaku is king, and he has finally found his queen, but she won't go down without a fight.
Shelby is not caught at first but finds herself trapped and rescued by a blue coral. Vagan has been watching and waiting for Shelby, and he has his chance to have her. Much more about the origins of Nagas is explained in this story.
Overall well-written stories and world-building. These were my first books by Naomi Lucas, but I will be getting more and moving on to the next in this series.
