Sequel to Martin Greeneyes - Following their return from the campaign against Swartt Sixclaw and the liberation of Mossflower from Tsarmina's Tyranny, the creatures of Salamandastron and Mossflower settle into a newfound, if occasionally tenuous, peace. As time passes and the scars of war fade into memory the victors move on and prosper, each seeking to carve out their own place.

Verdauga Greeneyes made a pledge to his Master-At-Arms, Luke, that he would look after his young son Martin. And look after him he does-by taking the young mouse in as his son and raising him alongside his own children. Now, as Martin grows up in a Mossflower ruled by wildcats, he must carve out a place for himself as both the son of Lord Verdauga and Luke the Warrior.
