Stephanie Harrington always expected to be a forest ranger on her homeworld of Meyerdahl . . . until her parents relocated to the frontier planet of Sphinx in the distant Star Kingdom of Manticore. It should have been the perfect new home ? a virgin wilderness full of new species of every sort, just waiting to be discovered. But Sphinx is a far more dangerous place than ultra-civilized Meyerdahl, and Stephanie's explorations come to a sudden halt when her parents lay down the law: no unsupervised trips into the wild! Yet Stephanie is a young woman determined to make discoveries, and the biggest one of all awaits her: an intelligent alien species. The forest-dwelling treecats are small, cute, smart, and have a pronounced taste for celery. And they are also very, very deadly when they or their friends are threatened . . . as Stephanie discovers when she comes face-to-face with Sphinx's most lethal predator.
