Introducing two novels of elvish lore and modern noir - Beyond World's End and Spirits White as Lightning - brought together for the first time by bestselling Mistresses of Urban Fantasy Mercedes Lackey and Rosemary Edghill! Sieur Eric Banyon, Knight and Bard to the court of the Queen of Elfhame Misthold, moves back to the Big Apple to take care of unfinished business. However, a normal life doesn't seem to be in his immediate future as he quickly discovers his Manhattan apartment has unique features, including a living gargoyle named Greystone and four Guardians who have sworn to protect New York from evil. And soon Eric discovers that unscrupulous researchers have created a drug that unlocks magical powers in humans - a drug that is 100 percent fatal over time. And now something evil from Underhill has other plans and seeks to use the temporary human powers to dominate World Above. But this is one bard who is going to let no such thing happen.
