Harper dividiu A Dance With Dragons em dois volumes para o mercado do Reino Unido: você vinculou a primeira parte, Uma dança com dragões: sonhos e poeira . A segunda parte é Uma dança com dragões: depois da festa . Bantam publicou o livro inteiro em um único volume.
Não tenho conhecimento de quaisquer diferenças no texto e na página da AWOIAF para A Dance With Dragons também não menciona:
Post-publication split into Dreams and Dust and After the Feast
A second form of split occurred involving A Dance with Dragons; while the book has been originally published as a single volume in the middle of 2011, starting around March of 2012 many English language editions were designed as two volumes (a similar decision to that taken in A Storm of Swords. The first half of these split editions are subtitled "Dreams and Dust", while the second half received the subtitle "After the Feast", supposedly because they include chapters that happen chronologically after the end of A Feast for Crows.
