Those familiar with McCaffrey and Scarborough's first SF trilogy about life on the sentient planet Petaybee will best appreciate this solid start of a new series, which picks up where Power Play (1995) left off. Murel and Ronan, the precocious twins born to Maj. Yanaba Maddock-Shongili, administrator of Petaybee, and geneticist/selkie Dr. Sean Shongili, lead an idyllic, if frigid, life on the icy planet for their first eight years.
More episodic than its predecessors, McCaffrey and Scarborough's finale to the charming Acorna saga will please the two authors' many fans and lovers of horses and cats generally. Last seen in Acorna's Rebels (2003), the unicorn girl has finally located her missing life-mate, Aari, though his exile in time has resulted in a disturbing personality change.
This SF team's earlier novel, Acorna, introduced the alien girl Acorna, an orphan rescued and reared by space-faring humans. Though generally human-shaped, she shares some features with the unicorn of myth--notably, a forehead horn that can heal and purify. Now Acorna blasts off with human friends in search of her own race, who shortly turn up looking for her. These gentle, horned nonhumans are fleeing other aliens who are wanton murderers and torturers that resemble huge cockroaches.
