A Goodreads user asked:
End of the series?
Levi Coren Fire takes place before Graceling, which takes place before Bitterblue. The exact connection between Leck's falling and his appearance in Monsea is not exactly explained, but Leck as a character is discussed in greater depth and all three books are connected quite nicely. I don't know if this is the end of the series, but it seems unlikely to me. There are plenty of opportunities for more stories to be told.
