The Girl and the Gargoyle: Book Two of The Girl and the Raven Series

Being half-witch/half-demon and dating Marcus, a gargoyle and demon enemy, is complicated enough for Lucy. She can almost tolerate Jude, her demon father, forcing her to undergo combat training. But when Marcus's long-lost family returns to Chicago, her world begins to crumble. Marcus's mother wants him to leave to join the gargoyle clan; his father wants him to help kill Jude. There's one major problem with this: if Jude dies, Lucy dies.

Marcus will do whatever it takes to save Lucy and her father. Meanwhile Lucy has her own plan and with the aid of a surprise newcomer, seeks help from the most unlikely-and dangerous-source.
