Melting Stones, a fantasy novel by young adult author Tamora Pierce, was released by Full Cast Audio as an audiobook original in October 2007, and was released in print form by Scholastic in the summer of 2008.
The book takes place after the events of Street Magic and the 2013 novel Battle Magic, and around the same time as the 2005 novel The Will of the Empress. It follows characters Evumeimei Dingzai and Rosethorn, former travel companions of Briar Moss, in their journey to the Battle Islands to investigate the death of the local plantlife and an impending volcano eruption.
It was Pierce's suggestion that she write an original novel for Full Cast Audio, and when she first heard young actress Grace Kelly read the part of Evvy during rehearsals for Street Magic. The author decided to recast what she had already written from third to first person so that Kelly could actually narrate the recording.
Bruce Coville, publisher of Full Cast Audio, served as editor for the text, and Pierce herself directed the recording.
