Catherine Asaro's Saga of the Skolian Empire has quietly become one of the most interesting, ambitious, and popular science-fiction series since Dune, captivating readers with its complex universe, its diverse cast of sympathetic characters, and its imaginative blend of hard SF, future history, military SF, space opera, family saga, and romance. Spherical Harmonics is the seventh book in the loosely organized series.

A woman comes to consciousness on a world she doesn't recognize, and fades out again--literally. As nonexistence and awareness alternate, the woman regains her memory, realizing she is Dyhianna Selei, the Ruby Pharaoh, titular head of the Skolian Empire, who was destroyed in a star-spanning battle that ravaged both her empire and that of its enemy, the Aristos. Instead of dying, Dyhianna was transported to a distant world via the quantum-mechanical universe of Hilbert space--and now she is in danger of disappearing permanently into that nonphysical universe. And that isn't her only problem. Her husband has been physically and psychologically scarred by his captivity in Aristo hands. She may have to overthrow the elected government of her own Empire in order to resurrect it from the ashes of the Radiance War and defend it from the powerful Aristos.

Spherical Harmonics follows (and sometimes overlaps) the events in The Radiant Seas, 031286714XThe Quantum Rose, and Ascendant Sun. Other books in the series include Primary Inversion, Catch the Lightning, and The Last Hawk. --Cynthia Ward -- From Amazon.com Amazon.com Review
