Having read (and loved) Shinn's first book about the planet Samaria, I was thrilled to find a sequel. Back to a world where angels fly and their song fills the skies, many years after the exciting and romantic events of Archangel. In Jovah's Angel, the weather patterns on meteorologically-unstable Samaria are deteriorating, and the only voice that seems to be hearable by Jovah, the overseeing "deity" of the planet, is that of shy, scholarly Alleluia, now forced by circumstance to play the role of Archangel, taking the place of a brilliant, injured predecessor. And political brilliance is sorely needed on Samaria, as the different factions jockey for top position, as technological advances are made (and resisted), and the weather worsens (and worsens), as knowledge is lost (and regained). Shinn is, as always, excellent in her society-building---she postulates a set of circumstances and characters and then rings the changes, inviting us along to see what happens...and it's a wonderful trip, really an engaging and wonderful book. Not dissimilar to Anne McCaffrey's Pern books, in its basic premise, but rather stronger in its depiction of a social-religious- political cultural matrix. And her depictions of the glories of human song are amazing and original. Very well done!
