The World Apart series was published in 2014-2015 and consists of four books: Crossing the Line, Towing the Line, Blurring the Line, and Walking the Line. Each title plays on the concept of boundaries, whether cultural, geographic, or personal, that the couples must navigate.
The “line” motif gives the series a thematic unity while allowing each book to explore a different type of divide. Marsh uses the concept to create varied romantic conflicts across the four entries.
