The five young Tanquerays live at Tanqueray Manor on the Isle of Summer, next door to Zerenity, their aged and loving aunt. Zerenity has always been a constant in their lives. When she goes to glory, she leaves a legacy that has far-reaching consequences. Ancella has found the love of her life, Guy is changing quickly, Horry has a new best friend he'll not see for a while, and the twins are unhappily estranged. What is wrong with Robert and Rupert? Only they know, and they have no idea how to mend it. The enigmatic piper, Tamhas a'Phiobaire, meets Robert and gives him a peculiar hint. But perhaps the answer to their problem lies under the stairs. This is Robert's story.
