The third and final volume in the House of Serpents trilogy, from New York Times-bestselling author Lisa Smedman Medusanna is a priestess of terrifying power and ambition. Never satisfied, she convinces the Se'sehen-a yuan-ti tribe from the distant jungles of Chult-to serve her growing cult of Sseth, who specialize in dangerous games of deception, poison, and murder. It is in the Sseth's foul plane of Smaragh that Karell, a yuan-ti half-blood, lies trapped and desperate. Her only hope for rescue and survival is Arvin, a mind-mage of growing psionic gifts. But time is quickly running out for Arvin to find her-and with each passing minute, the House of Serpents slithers closer to destroying their last hope for freedom.
