When a routine hanging goes wrong and a murderer somehow survives the noose, the man announces he is an immortal. And not just any immortal, but Cayal, the Immortal Prince, hero of legend, thought to be only a fictional character, a figure out of the Tide Lord Tarot, the only record left on Amyrantha of the mythical beings whom the part-animal, part-human Crasii believe created their race. Arkady Desean is an expert on the legends of the Crasii. At the request of her childhood friend, Declan Hawkes, the Kings Spymaster, she is sent interrogate this would be immortal, hoping to prove he is a spy, or at the very least, a madman.
Arkady is in exile in Ramahn, the repressive Torlenian capital, where she makes some unexpected friends and some powerful enemies, all of whom seem bent on using her to wreak vengeance on each other. Back in Glaeba, the King’s Spymaster, Declan Hawkes, has recruited the canine Crasii, Warlock, to spy on the Tide Lords attempting to steal the Glaeban throne. Warlock, desperate to get back to his pregnant mate, is forced to witness an unthinkable crime.
