Peter Antilys, Lord Commander of the royal army and veteran of countless battles, has been tasked with protecting the fortified city of Greyheart from an enemy he's never faced before. Elves have been spotted leaving their forest territories for the first time in more than one hundred years, and all reports of their movement declare they are marching for war. Villages near the elven border are losing their inhabitants, scouts who venture out never return again, and anyone who has seen the elves and survived bear strange and grievous wounds. Now Peter must prepare a city to stand against a foe they never thought they'd face, but will they outlast the onslaught?
