In a modern world with no idea it is happening, the faerie realm and human magi prepare for a savage war that will break a stalemate going back to the time of King Arthur. Elizabeth Bear mostly takes the side of the fae through Seeker, a once-human bound to the Elf Queen who must steal humans at her command. Bear uses so many lush metaphors to describe the physical world experienced by magical beings that it was tough to consciously take them all in, but the cumulative effect was mesmerizing. Most of the novel consists of powerful otherworldly creatures readying for war and engaging in diplomacy with allies, enemies and undecideds, which reminded me favorably of Roger Zelazny's Chronicles of Amber. This builds to a harrowing and dramatic conclusion. The star of the book is a kelpie (water horse) nicknamed Whiskey. Seeker controls him by knowledge of his true name and they develop a deep relationship despite the fact he's allowed three chances to kill her, which he reminds her of often.
