The world is divided by the Line of Limit. To the north are the Tokkebifire people able to manipulate flames as both weapons and illusions; Rekon - giant birdmen with immense strength and warrior acumen; and the humans - as divided as the other races are unified. To the south are the Nhaga - a reptilian people who relinquish their hearts for immortality. For centuries, the races didn't cross that line, but change is in the air. A Nhaga is being sent North...and a trio is being dispatched to make sure this agent from the South makes it out alive - one from each race. But the illusion of a simple journey is quickly dispelled by the fact that the Tokkebi is merely a scholar, not an adventurer; the Rekon is deathly afraid of water; and the human hunts and eats Nhaga. And when the Nhaga they're supposed to be escorting out of the Kiboren forest is murdered, the one sent in his place turns out to very much have a heart - meaning he's quite vulnerable to the dangerous exodus. The four must quickly forge an alliance and shed the distrust and prejudice that plagues them if they are to survive. And just as crucial, they must figure out what this mission is actually about, because unbeknownst to them, the very fate of the world might rest on this one Nhaga making it to the North intact.
