Taking the position of nanny to twin five month old nieces of the former defensive center for the New York Scorpions, Sierra Evans must hide the secret she has carried alone. Sierra is the biological mother of the twin girls that she gave up at birth for their best welfare. A one night mistake with a married man left Sierra unable to provide for her babies along with paying for nursing home care for her father. Even though a nurse, her income would not cover it without working two jobs. Applying and receiving the nanny position offered by Cooper London gave her the opportunity to be there for her babies when the adoptive parents, Cooper's brother and wife, are killed in an accident and Coop is given custody.

Less than 24 hours and they are sleeping together with Sierra's intentions to eventually tell him about her past liaison. Falling deeply in love but holding back on declaring themselves, Coop is secretly intending to marry Sierra. Everything moves forward until Coop receives delivery of his brother's possessions which include the birth records surrounding the adoption of the infants. The details of the biological mother are revealed to Coop and Sierra's deception uncovered. The true identity of the father now threatens to tear them apart forever and Sierra stands to lose not only her children but the man she is desperately in love with. So as not to tear the infants away from the mother they need and love, Sierra stays under Coop's condition she is once again "just an employee".

Sierra's devoted love to her babies forced her to give them up in order to provide them the best life they could have with all the opportunities she herself could not afford. Coop, a famous and very rich eligible man, is intrigued with Sierra's demeanor of displaying no intentions of trying to trap him like every other female.

THE NANNY BOMBSHELL is a very cute and well written story of the sacrifice of a young woman who struggles to do the best for her babies even when it means giving them up and finding love at the same time.
