Mark of the Succubus Series by Ashly Raiti

Maeve, a succubus-in-training, is sent to the human world by her mentor, Veril, to learn how to blend in and hone her skills of seduction. However, things get a little complicated after she meets Aiden, a smart but unmotivated student at her new high school. Unfortunately for her, Sylne, the head succubus of the Demon World, has set a spy on her former protege to catch any missteps.

Maeve unfortunately must hurt the one person that she cares for. She now has a choice to save her first target or defy demon law! If she tries to bend the Rules, there may be a chance that neither of them will survive.

The race is on for Maeve, Aiden and Devin to find a way to trick Sylne into betraying herself, but without Veril around, their efforts might be futile. Junael adds a formidable and highly knowledgeable component to the odd team, but even his advice and skill may not be enough. As a newly licensed and still-inexperienced demon, Maeve and her magical skills may be their best hope!
