The Glass Butterfly

For nearly a decade, Felicity Lonsdale has lived as a much older dowager, selling rare caterpillars to conceal a tragic past and raise her late brother's daughters on an isolated Irish estate. Her carefully constructed life is threatened when the earl's estranged son arrives, intent on claiming his inheritance and exposing her true identity.

Meanwhile, disgraced viscount's heir Nick Thornton seeks a mythical transparent-winged butterfly on the estate, hoping to contact his deceased wife and child for forgiveness. As Nick investigates the mysterious butterflies, he and Felicity form an uneasy alliance against the earl's son, drawing them closer to each other's hidden sorrows and the ghostly secrets within the castle.
