Retra braves the intense pain of her obedience strip, and stows away to seek her brother Joel, gone two years for Ixion - island of ever-night, ever-youth and never-sleep. Retra is a Seal – sealed minds, sealed community - no craving for parties or pleasure. What are the Night Creatures Retra can see in the shadows? What happens to those who grow too old for Ixion? Without Joel, is her eternal bond with a Riper guardian enough to save her? Listen well, baby bats. Burn bright, but do not stray from the paths. Remember, when you live in a place of darkness you also live with creatures of the dark.
