Acorna is the touching story of a young alien girl with extraordinary powers who is found drifting in an escape pod by the crew of a human spaceship. She is an unknown species to them, but reminds them of a unicorn, so they name her ‘Acorna’, and after failing to find her family or home planet, the three young miners take her under their wing. We follow her swift maturation from infant into adolescence, the love that she inspires from all who meet her, and the determination with which she seeks to right the injustices of the worlds that she travels through. This is the first novel of the ‘Acorna’ series, and Anne McCaffrey has again succeeded in capturing our imaginations with another unique story. I could barely put it down, and ended each chapter only to carry on reading, because I had to know what happened next! Anne McCaffrey fans will not be disappointed, although the writing style is perhaps aimed at a slightly younger target audience than the ‘Dragonriders’ series.
