Fire & Blood by George R. R. Martin was published in 2018; it is a fictional history book set in the world of the author's as-yet-unfinished fantasy series A Song of Ice and Fire. A second volume of the book, with the planned title Blood & Fire, is expected, though Martin has said that he will not publish it before the release of the next novel in the ASOIAF series, The Winds of Winter.

This is an independent multiple-choice market; each option will resolve YES if the book is published (not just announced) before the year listed in the answer. It doesn't matter whether or not the second volume is split into multiple books (as some fans have speculated); the publication of a single sequel to Fire & Blood counts. Posthumous publications, including those involving another living author, (like the final books in the The Wheel of Time series) also count.
