''Spherical Harmonic'' is a science fiction novel from the Saga of the Skolian Empire by Catherine Asaro. It tells the story of Dyhianna Selei (Dehya), the Ruby Pharaoh of the Skolian Imperialate, as she strives to reform her government and reunite her family in the aftermath of a devastating interstellar war. == Plot summary == ''Spherical Harmonic'' is a first person narrative told from the viewpoint of Dyhianna Selei. Although an elected Assembly governs the Imperialate, in ages past the Ruby Pharaoh ruled as absolute sovereign. Selei is the descendant of the ancient pharaohs, and is considered the titular ruler of modern Skolia. ''Spherical Harmonic'' takes place following the Radiance War, a conflict fought between the Imperialate and the Eubian Concord, an empire ruled by a rigid caste of narcissists called Aristos. The Eubian economy is based on slave trade, which the Aristos seek to expand to the Imperialate. Just prior to the opening scene of ''Spherical Harmonic'', Dyhianna Selei escapes a Eubian military force by stepping into a Lock, a singularity that defines the boundary between two universes. In mathematical terms, she has entered an alternate dimension defined by the functions known as spherical harmonics. As the book opens, she is "coalescing" on a moon called Opalite. She reforms in partial waves that transfer her from one universe to the other. Some prose in the book is written in the shape of the sinusoidal functions found in the spherical harmonics.〔(Text with sinusoidal prose poems )〕〔Asaro describes the mathematics of spherical harmonics in an essay at the end of the novel.〕 As Selei fades in and out of existence, in danger of disappearing, she slowly recovers her memories about her identity and history. She manages to activate an emergency protocol secretly established on the moon for her protection. As a result she is found by Jon Casestar, an admiral in the Skolian Fleet, and Commander Vaz Majda, an elite fighter pilot who is also her sister-in-law. Once aboard an ISC battle cruiser, Selei strives to reunite the Ruby Dynasty and find out what has happened to her people. The book follows her attempts to resurrect the Skolian military and government.〔(Review by Science Fiction critic Cynthia Ward )〕 Selei also struggles to discover what has happened to her son Taquinil and her husband Eldrinson. Her plan to go to Earth and free members of the Ruby Dynasty being held captive there, including Roca, her sister and heir, meets little enthusiasm among her top officers, as it can be seen as an act of war. Unable to trust anyone, Selei ends up seeking to overthrow the elected government of her own empire so she can rebuild it from the ashes of the war. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spherical Harmonic」の詳細全文を読む スポンサード リンク
