Trading Places (fern Michaels)
Aggie and Lizzie Jade are "mirror twins". They look the same but have opposite personalities. Aggie, quiet and reserved is a police officer living in Atlanta. Lizzie is an outgoing, strong willed professional gambler, Living in Las Vegas.
After a near death shooting, leaving Aggie's partner dead and K-9 shot, Aggie is seriously wounded. She decides it is time for some rest, relaxation, and grow some organic vegetables. She calls upon her sister Lizzie for help. After all they are twins, and used to pull this off all the time. They decide to trade places, and soon Lizzie becomes Aggie.
Both sisters are convinced this is an inside job, and every police officer is suspect. What they uncover leaves the sisters with little choice. Fast paced, with a bit of romance, I found trading places to be a fun read.
