Innkeeper's daughters Adele and Eleda are "mirror twins"--identical twins whose looks reflect each other's--and their special talents are like mirrors, too. Adele is a Safe-Keeper, entrusted with hearing and never revealing others' secrets; Eleda is a Truth-Teller, who cannot tell a lie when asked a direct question. The residents of Merendon often turn to the twins-- especially their best friend Roelynn Karro, whose strict, wealthy father is determined to marry her off to a prince she's never met. When the twins are 17, a handsome dancing-master and his apprentice come to stay at the inn, and thus begins a chain of romances and mistaken identity that will have readers utterly beguiled.
