When Desah Ssyn arrives on Earth, all he wants to do is carry out his assignment, then get home before his Chara cycle begins and all he can think about is sex. He never counted on being attracted to Federal Marshal Nevada Cisco, his guide and partner while on Earth, or the strong feelings he's developing for Sophie Gibson, the woman Nevada is assigned to protect. Nevada Cisco isn't pleased with his new assignment--until he meets Desah Ssyn, and his world is turned upside down. Soon his orders to cooperate with the alien take on a whole new meaning. For Sophie, being in protective custody isn't bad. When the two men protecting her are gorgeous, and one of them is an alien in heat, how could any earth-born woman deny the call of the alien's Chara time? Or for that matter, how can any earth-born man? Certainly not Sophie and Nevada. But there are dark undercurrents threatening to tear the threesome apart, just as they are learning the joy of sharing their bodies with each other. Chak Enif, the alien drug dealer with a secret link to Desah, and Sophie's ex-boyfriend, Brian, have found them. Soon the chase is on, and the alien drug peddler is not about to allow Desah to complete his assignment without a fight. Alien sex is the powerful aphrodisiac that binds them together, but will they survive the forces determined to tear them apart?
