On far away Sarran, the Warriorpair Jonal and Tonas, along with the rest of the planet's males, lost their Fem when the Zyptz unleased a toxin that killed only females. Sarrans mates in Triad, two males with one female, and without fems, their civilization stared extinction in the face. But the Sarrans are tough and smart. They searched the galaxy for a genetically compatible species and found Earth. They were told the Earthen fems were an inferior species, with many unable to establish the psychic link essential to the triad bond, but they had to try. En route, from as far out as the asteroid belt, they heard fem voices calling to the mates. Success! But their joy is short-lived, because the human fems are in pain—they are dying. The Zyptz found Earth before the Sarrans and unleashed their toxin. Admirals Jonal and Tonas are determined to obtain a fem at almost any cost, and rush to save Anya, because they've already mated with her in their minds.

Sequel to The Sarran Plague Syn Sinclair is one of the women taken from Earth to Sarran to replenish the fem population. While still en route on the Brightstar, Syn meets the Sarran Elder, TeZaron and thinks he looks down on her because of her checkered past. Upon landing, Nafer, TeZaron and TeBron's offspring, recognizes Syn as his "Mommie," something the Elders didn't realize because of the mind blocks they had placed on each other to ensure the success of the mission to Earth. Syn, a former prostitute and drug addict, left home at sixteen because she was sexually abused by her father and his friends. She made it out of the gutter and into the halls of higher education, getting her Masters in Psychology with a specialization in PTSD. Now she’s afraid her WarriorPair won’t accept her because of her past. As soon as they bring her to their home, she works to gain their respect. Supported by her WarriorPair and their son Nafer, Syn settles into her new household with grace and energy. She is happy, very happy, except for one niggling doubt. Although she knows her Warriors have accepted her, she worries how others will view her new social position on Sarran. In particular, a fem from Syn's past lets everyone know she’s unfit to BondStir with the High Lords. Madeline Dixon-Howard sees Syn as a blight on the new society. Additionally, an even deeper evil is hiding in the Sarran government. Someone has sold information to the roach-like Zyptz, someone who planted a bomb and listening devices in the homes. Someone doesn't want Earth women to mix into the Sarran genepool. Syn's insights as a psychologist combined with her new Psy powers just might help her Warriors find out who the traitors are and devise a plan to capture them.

The Sarrans are back and they are angry. They heard from their fems that women on Earth are abused. Horrified, they made it part of their mission to rescue these women from their abusers. Mark and Juraens lead the delegation to negotiate for fems, cats, chocolates, and coffee in exchange for gold and Sarran technology. They have an extra incentive—they both sensed their Bonded is on Earth. Sara Hayden, the wife of up-and-coming politician, is being beaten with a baseball bat when Mark and Juraens hear her son’s psychic scream. They teleport to render aid and discover Sara is their fem. Now they must get her and her son Michael away from her abusive spouse, and convince her father, senator and would-be presidential candidate Sam Johnson, to join them. Fortunately Sara’s cat Chou adopts them wholeheartedly. While they are recruiting cats for Sarran, a beat-up tomcat named Aloysius and a grey kitten called Shadow join them on their quest.

The Sarrans return home from Earth in triumph, having gained many new Earthen fems, coffee, chocolate, and cats. Senator Samuel Johnson joins his grandson Michael, his daughter Sara, and her WarriorPair on Sarran. To his delighted surprise, he bonds irrevocably with Tarin, one of Sarran's top engineers. Tarin had been bonded before and thought he would never experience a bond again, yet Sam's love gives him a new lease on life. Now they only hope the Goddess has a fem for them. Then the Sarran Elders host a mixer for Sarran warriors to meet the Earthen fems. Margaret Mary O'Neil, Meg to her friends, is a talented woman who fled to Sarran like so many Earth women looking for a new life. When she meets Sam and Tarin, her life changes forever. But while things are looking up for the Sarrans, with new babies being born and WarriorPairs settling down, their enemy the Zyptz are relentless in their efforts to wipe them out. When the Zyptz attack both Sarran and Earth, the mutual dependence between the two becomes ever more evident.
