The River King - The Demon Door, #4

SOMETIMES LOVE DOESN'T CHANGE THE WORLD. SOMETIMES IT CHANGES ALL OF THEM. Rhuun, the half-human and wholly-reluctant prince of the demons, has finally reunited with his fiery Lelet. It's too bad they must hide behind a facade of icy indifference to fool those who are determined to keep demons and humans apart...by any means necessary. There is more at stake than bringing the miracle of rain back to Eriis.
It's not just sand and lost royals poised to come through the newly-opened Door. Something ancient is hungry, and fat, complacent Mistra won't stand a chance. Even worse, whispers and shadows speak of blood magic that could destroy not just The Door, but all Doors-forever-barring the way home for lovers and enemies alike. Will the love Rhuun and Lelet have moved worlds to share be the very thing they must sacrifice to save their worlds?Full of her signature blend of exquisite world-building, sly humor, and poignant prose, The River King is the gripping conclusion to Kim Alexander's critically-acclaimed Demon Door saga.
