1993’s portal fantasy Sea of Wind is the second volume in Fuyumi Ono’s Twelve Kingdoms series. The 2007 English language edition was translated by Alexander O. Smith and Elye J. Alexander.
Taiki spent his childhood wracked with guilt for continually disappointing his judgmental grandmother, who never fully explained what he had done wrong. Small wonder that the ten-year-old leapt at a mysterious summons from another realm. Bye granny! Destiny awaits!
Destiny and, it turns out, heavy responsibilities and great danger.
