Starfall

Tynan and Kelton are twins and warriors with a special Dareen military unit that rescues women who are being sold by Malderan slavers. They arrived on Earth to try and stop the abductions of human women. Just as they arrive they come across a group of slavers that are trying to abduct a woman, Megan Townsend. They had planned on just allowing her to leave, but questioning the slaver that tried to abduct her reveals that they have to find her for her own protection. Once they find her they decide they would like to make her their mate. Megan has a dark past that makes it hard for her to trust anyone. Kelton, being a strong empath, senses this and convinces Tynan that they need to move slowly with her. They use their senses and knowledge of the Dareen form of BDSM to help her recover from her traumatic childhood and be able to trust them.
