But her life becomes far more complicated once she meets the man she has been tasked to expose. Luna finds Rodrigo de Rueda Calderon to be a brilliant, outspoken oncology specialist with irresistible, dark gypsy looks and a devilish sense of humour. The pair are irrevocably drawn to each other, but how can she give herself up to a passion that threatens to topple all reason?
