If this is the first work of mine that you have read you may have been a little confused as to who these people are. This isn't the first book in this universe, so you may want to read that one first! It's called The God Capturer. It's not a romance book so if you just want that this is your only option for now. However, if you do want to read the God Capturer or at least get some more information on it, it is already published!
Hope you have enjoyed and hold tight for the next book in The Mortal God Series: The Daughter of Bellona!
