Owning the Stone-Chance Protection Agency has its perks. It's a profitable company that allows Ramsey and Keilah Stone to enjoy the finer things in life; however, it has also added an element of danger to their otherwise normal lifestyle. When Keilah was a field agent, she was an excellent marksman, known for being fearless when it came to protecting her clients. Now that she has a baby daughter, she's lost that competitive edge and longs for a slower life. That might not be possible, though, when the return of a shady ex-lover brings chaos into Keilah's life. At home, Ramsey is a warm and caring father and husband, but on the job, he finds it necessary to maintain his tough persona as an ex-military officer. When an unexpected tragedy darkens his doorstep, he finds himself in a cat-and-mouse game with a dangerous assailant. He will be forced to make some very difficult decisions in order to protect his family. Essence best-selling author Darrien Lee delivers another page-turner with Precious Stones.
