Duty compels Ben to find this man's killer. But with one look at the unconscious China, Ben's desire to catch the murderer escalates, and he vows to avenge this beautiful, unfortunate woman. Before China even wakes up, Ben is more than halfway in love with her, and his feelings only intensify when she recovers. But there are a few problems standing in their way - as a witness to an unsolved murder, China is still very much in danger. Even more problematic is the fact that China, a formerly abused child, doesn't believe herself worthy of Ben's love.
Butterfly is mostly sugar, with a little bit of spice.
The spice derives from glimpses the reader sees of several individuals who may or may not be prime suspects in the murder case. These dubious persons include a Texas Senator who wants to be President at any cost, and his notorious mother, who has never lost her white trash roots. There's enough adultery, hypocrisy and other shenanigans to let the reader know that this is modern romantic suspense. But the relationship between China and Ben is pure saccharine. China may be poor and pregnant, but she's sweet and gentle, with insecurity her only failing.
