Jake was born with nothing and clawed his way through life as the leader of a mercenary band, only to be used and discarded by the nobles he served. Death should have been the end of his ambition, but he wakes again in an entirely different body: the third son of House Valdek, a grand ducal family whose influence rivals the imperial throne.

Now surrounded by the bloodline, status, and talent he once lacked, Jake refuses to live quietly as a pampered noble. Behind the manners of a young aristocrat remains the sharp mind of a battlefield survivor, and he intends to turn his second life into a climb toward the very top.
