The setting is Rainshadow, on planet Harmony. Aliens have left the planet long ago, leaving behind ethereal cities and mysterious technology that some humans can use. Ella has a talent - she's a Siren, and can sing paranormal harmonies that kill. That doesn't make her much suited for dating, until she meets Rafe, who knows what she is yet isn't repulsed by it.
Siren's Call is the second book I've read by Jayne Castle and I definitely see a pattern here. Castle's hero's are steadfast men with a secret or two, but nothing too dramatic. Her heroines are ladies with dreams and goals, usually have a business of their own, and aren't very reticent in going for what they want. Castle's characters and stories are comforting. Nothing too bad happens, just enough to create some suspense. The romance gurgles along nicely without any overly contrived happen-stances keeping the hero and heroine apart. The science-fiction/paranormal element is fun, easy to understand, and just interesting enough to provide a nice backdrop for action.
Siren's Call is probably best described as a powdered sugar doughnut that features so prominently in the story.
