so the story starts off at Lucas's house explaining to Claire and Matt her supernatural powers. after that she is caught too close to Lucas and castor goes off his nut and sends Helen home then practically yells at Lucas to stay away from Helen and to force himself to hate her. whilst Lucas is being told that Helen is going back to the Underworld better known as Hell to try and complete an impossible task. but she finds Orion down there instead who tries to help her complete it since he is the only other person allowed down there. so while Helen is trying to figure out why Lucas is avoiding her she is desperately falling for Orion who she doesn't yet know is her mother slaves then some demon starts attacking her in the human world so that ares can kill her in the underworld but doesn't yet realize that Orion is the one saving her and not Lucas.
so i wont tell you the ending in case you end up liking i but i personally really disappointed i didn't hate it but it really could have been better.
