Maeve soon meets Aiden's quirky best friend, Devin, and his snobby, superficial girlfriend, Sandra, and learns about the wonders and perils of the human world.

There is a demon on her tail who will do anything in her power to catch Maeve breaking the Rules of the demonworld, all in order to increase her own wealth and social status.

And when she ends up falling in love with the same mortal that she has placed her Mark on, sentencing him to die, only trouble can result from such a blatant breaking of demon law.

Her quirky habits mark her as someone just learning the ways of a culture, and her utter inability to lie convincingly adds to the peculiar image.

Indecisive, mild-tempered, and a bit withdrawn, Aiden rarely protests when others make his decisions for him, drifint along in whateverdirection he is pushed with no real enthusiasm.

Al he really wants to do is play guitar but only his best friend knows he is good at it: instead he puts a weak effort into things he does not truly care about, avoiding conflict at the expense of his own dreams.

Desiring a certain title, and the power, fortune, and recognition that comes with it, Sylne placed an illegal Human Spell on the Imp, Junael, forcing him t spy on her old student, Maeve, expecting the girl's nature would cause the younger succubus to slip just enough to use for her own selfish purposes.

Written by Ashly Raiti and illustrated by Irene Flores, Mark of the Succubus was published by Tokyopop in three volumes from November 8, 2005, to July 9, 2008.
