A Moth in Darkness — Frances Pauli

The boundaries between the worlds have fallen. Forced to integrate the creatures of fantasy into real life, humanity struggles against its disillusionment, prejudice and an inevitable feeling of inadequacy. Once an agent for the embassy that mediates between the worlds, Elizabeth Larson has abandoned her past and slipped into a world of nostalgic addiction to fairy revels, dancing, and the dark lure of her own memories. But when Lockland Sheen, her former partner and lover, goes missing, she is pulled reluctantly back into service. She must venture once more across the borders, into the land that haunts her, facing a string of gruesome murders, the imposing Sidhe rulers and her own addiction in the process. While the Embassy's agents attempt to soothe tensions between the races, Liz and her new partner search the fairy realm for Lockland. Fighting the constant temptation of the revels, they piece together the trail of an unknown enemy. But the longer they follow it, the more it appears that the man they came to rescue is more villain than victim. And the more they rely on Elizabeth's ties to the fairies, the closer she inches toward the madness that lurks behind her fantasies.
