A Gathering of Gargoyles is by Meredith Ann Pierce. This is the second book in the Darkangel trilogy. Aeriel has freed her Darkangel from his curse, but the White Witch is far from defeated. Aeriel must now leave Irrylath and continue her quest to overcome the witch and the other darkangels. She has been given another riddle to solve and finds friends and enemies along the way. This is a fascinating trilogy and quite an enjoyable read. It is darker than Twilight, but without any problematic content.
