Tamlin once almost had everything until he lost it to his anger and vanity, and most of all, his obsession with keeping a memory of what once was alive. Now, he has nothing. No Feyre. No stability in his court. No will to see himself as anything other than a beast, for despite his actions during the war with Hybern, he remains painted as the one who caused the mess.
Haunted by the voice of his deceased mate, one day, while roaming the woods, he comes upon a bright light beckoning him. And within the blink of an eye, he finds himself somewhere foreign, loud, and full of weird gadgets -- weirder than Lucien's glass eye. In other words, he finds himself in our world, specifically in the United States, Wisconsin, where a fearless woman named Ziva Schroeder finds Tamlin and takes him in. Our world is run by faeries, of which Ziva is half, and angels, which Ziva also carries in her blood.
While Tamlin gets to experience modernness through the help of Ziva and her inner circle, the tug to return to Prythian soon becomes a warning because a familiar foe plans to resurface, more potent than ever, worse than ever, and only Tamlin has such knowledge of the plans. However, he also must choose between our world and Prythian.
