The Menagerie (series)
The Menagerie is a dark fantasy novel series written by Christopher Golden and Thomas E. Sniegoski. The Menagerie is made up of legendary characters, each with his or her own powers and mystical, mythical origins. Golden and Sniegoski have taken various characters well-known from literature and mythology and made them their own.
As described by Ace Books: They are beings of myth and legend. They possess powers beyond imagining. They are our only hope.
Meet the Menagerie - as hodge-podge a mix of other-worldly beings as anyone can imagine. But a sorcerer, a scientist, a sixteen-year-old demon, and the others all have one thing in common: a hunger for justice - no matter what the cost.
Book One: The Nimble Man
Behind the facade of a stately Boston brownstone, humanity's last defenses are being marshaled. Called to action by the enigmatic, brilliant man known only as Mr. Doyle, they hail from all planes of existence and are born from an array of supernatural and otherworldly backgrounds and bloodlines. But as the group struggles to come to terms with their shadowy pasts, personal demons, and conflicting loyalties, their greatest challenge awaits them.
Together, they will confront the minions of utter darkness, who have already begun their quest to resurrect the most malevolent of the fallen angels—whose wrath against mankind knows no bounds.

Book Two: Tears of the Furies
When word comes to Doyle of a series of inexplicable deaths in and around Athens—men and women turned from living flesh into cold stone—he dispatches the Menagerie to investigate. But he soon follows when he realizes that he has sent them into a far greater danger than he imagined. For the queen of the Gorgons herself has risen. To defeat her, the group will have to descend into Hell itself.

Tempted into sampling the horrific but thrilling existence of a full-fledged demon, Danny is on the edge of renouncing all that makes him human.
