Double Jeopardy is by KaLyn Cooper. This book takes place on Aragon Island off the coast of Panama. Blake Albright works for Guardian Security and was one of the assistant managers. He is surprised when Alex, the owner, brings in Ryleigh Davenport as an agent. She was hired by the co-owner Kaitlin Callahan as the first woman in the agency. Ryleigh was highly qualified and had just left Afghanistan after an illustrious career there. However, she was tired of her job there. At one point several years ago, she and Blake had an affair but she had left quickly and with no explanation to him. He couldn’t forget her.
A billionaire, Duke Wainwright, and his wife, Ella, are vacationing at an exclusive resort on Aragon Island for a week. Guardian Security has taken on the job of protecting them as they have received death threats. Blake Albright and Ryleigh Davenport are selected to protect them posing as their best friends. Ella had planned the entire vacation so she could spend time with her husband without any interruptions from work. This resort was unique in that it forbade the use of phones while there. The major problem they had was no one knew where the death threats came from nor who they were directed at, Duke or Ella? Upon arrival to their cottage, Duke was somehow poisoned while alone in the cottage. The arrival of Ella and Ryleigh with their escort was timed perfectly to save him. Then, while Ella and Ryleigh are scuba diving, someone spread chum in the area and brought in sharks to surround them. Ryleigh escaped being bitten by a shark by bare inches. Who was after the couple and why?
