As part of the ongoing Miami Book Fair International festivities, WLRN is giving readers a chance to co-author a story with Junot Díaz. Beginning at 5pm today, they will tweet out the first line to a story—provided by Díaz—from their Twitter account. Then readers will use the hashtag “#WLRNStory” to add onto Díaz’s line, and later each other’s lines, and ultimately the entire thing will unfurl before them.
