The Syrene Caper. SpaceColony Journals - The Next Generation, #2

Twins are supposed to share everything, but when her twin sister Azalure rescued Lorelei from Hans Grouter's breeding farm, Meredia couldn't help but feel a twinge of jealousy. She longed for the same bond she saw between her twin and her new daughter. Since Syrenes are always born as twins, they knew there should have been another Syrene girl, but she wasn't with the group of 3-year-olds rescued from Brisai.
Recovered records showed Lorelei was supposed to have a twin sister, Nerlisa, who was nowhere to be found but the family continued to search. Meredia's successful acting career brings her to the remote island of Sanduski for a publicity shoot. She didn't know this trip would reunite her with her long-lost daughter, Nerlisa. But their reunion is anything but peaceful, as a dangerous crew of pirate and drug runners has sights set on Nerlisa's unique Syrene diving abilities.
As Meredia struggles to become a mother and protect her new daughter from harm, she must also confront the truth about what happened to Nerlisa all those years ago. Will she be able to keep her daughter safe among a labyrinth of dangers?
