Black Shore of the White City (White City #1)

Jude Coffin enjoys the finer things in life: an exceptional wine, a good whiskey, non-menthol cigarettes, and a cute guy with a great ass. Despite being a Siren, or an 'aural captivator' for the supernaturally correct, he doesn't like paranormal politics, paranormal science, and certainly not paranormal activists.

Despite this, Jude and his similarly supernaturally-endowed twin brother Jason are lured to Chicago to undergo study at the controversial Institute of Supernatural Research. Jude remembers why he stays away from the paranormal world when the Institute takes his brother hostage. His only hope of getting him back is enlisting the help of Micha Bellevue, Chicago's leading paranormal advocate, and Sam Haain, fiery, possibly insane paranormal supremacist. Tangled up with these two clashing and decidedly sexy personalities, Jude gets a look at Chicago he never wanted: a city at war with itself, full of angry supernatural people, conspiracy, and murder.
