For Shanna, joining the Scout Corps had been a dream come true. The Scouts were charged with expanding their knowledge of Frontier, a hostile planet their ancestors had crashlanded on 300 years before. As the youngest in her class, Shanna struggles to find acceptance and respect amongst her older peers - a task made more difficult by the fact that she has not just one, but two of the colonists' huge feline companions, their starcats.

On a routine patrol, she and the other cadets are swept up in the greatest challenge yet to be faced by the settlers of Frontier. Now they find themselves on the very frontline of a war they knew nothing about, and possibly the Federation of Race's last chance against the hostile Garsal. Suddenly their world has changed, and in ways never dreamed of by Shanna and her fellow scouts.
