This “breezy” tale by the bestselling author “explores the bitterly antagonistic relationship between two sisters, and the murder mystery they become embroiled in” (Publishers Weekly). 
 
Soap opera writer Deborah Peltz can handle any kind of drama, except for her sister Sharon’s. A wedding planner in Boca Raton, Sharon thinks she has the answers to everything, but with three divorces under her belt, she should be the last person on the planet to dole out all that eyeroll-worthy advice.
 
Normally, Deborah survives by keeping her distance, safe in the bustle of New York, but when their mother has a heart attack in Florida, she drops everything to be near her. Burying the hatchet with her sister is a challenge in itself, but when they both fall for their mother's handsome cardiologist, winning him over and earning an invite to his place becomes an obsession.
 
But when they find him dead in his waterfront home, neither sister wants to be near the place. Now the prime suspects in his murder case, they must stick together to stay alive. Hiding out in the Bahamas may be their only chance—if they don't kill each other first…
