Abednego, as the first book of the Guardians Series, tries to introduce the different races and realms of the Guardians, primarily through the frightened and bewildered eyes of Samantha “Sam” Trent. When she meets Abednego, the interrogator and his organization are all she knows about Guardians or Nephilim, and she is understandably vehemently opposed to Abednego claiming her as his “keeper” or mate, a role that has more to do with accountability than the romance Sam immediately assumed it entailed. As the descendants of Angels, the Guardians aren’t offered salvation, so they each have a “keeper” who can invoke their name and take away their free will temporarily so they don’t fall into evil ways.
Of course, each Guardian she meets has a different philosophy on what exactly a mate’s responsibilities are, and even how appropriate it is to use someone’s name when they aren’t your keeper. More importantly, they each have to ask if a human mate can be trusted to weild the power of a Horse Lord’s name.
Abednego isn’t quite as far behind since he knew other Guardians centuries ago before the Hunts of the Middle Ages demolished his people and sent the other races into hiding. But a lot has happened in the time since, and worse, he has no idea what to do with a human mate.
That is, assuming the others’ antics don’t ruin what little chance he has left.
