No one holds a grudge quite like a faerie . . .

All Colin Leffee wants is to be left alone: to run his used bookstore in peace, and to quietly drink himself to sleep every night in an attempt to drown out the memories of eight-hundred-plus years of existence.

Unfortunately, when a sullen teenage changeling is flung out of Faerie and onto his doorstep, the long-suffering, wayward son of Titania knows his dreams of solitude are dust. Colin—or Lord Coileán, as he is known to the Faerie court—must track down Meggy, the love of his life, and figure out how her child ended up in Titania’s clutches to begin with.

But with family, it’s never simple. He finds Meggy, only to have her yanked into Faerie—and the doors between the realms slammed and locked behind her. Now, it’s not just her life at stake . . . but the fate of magic itself. 

Always the loner, Colin reluctantly joins forces with an intensely stubborn wizard, a young priest-in-training who fancies himself a knight, and his half brother Robin (the last most definitely not by choice) on a quest to reopen the doors and restore the balance between the realms. And with exiled queen Mab plotting in the shadows to take Titania’s throne, and the wizards of the governing Arcanum hiding their own agenda, Colin can’t be sure whom to trust—or whether he’ll live long enough to see the mission through.
