Hunting new elemental monsters that have appeared in Texas, Jake Everett and his team finally discover where these things are coming from. It seems that someone is altering the portals that normally lead to the fae realms to allow creatures to come through from other worlds. They suspect the Dark Prince is behind it, but they don't know how he's achieving it.
Jake receives a surprise visitor from the Seelie Court. The delectable Emelia gives him a magical invitation from her rulers. He knows he'll have to open it eventually, but doing so will embroil him deeper in his quest. For now, he has another job to do. He'll have to answer their imperial summons when he's finished with his current mission.
The Hunter Elite join Jake and his team on a job to take down some particularly nasty monsters, then Jake has no choice but to head to the fae realms. Once he has the gem that will allow him to close the dragon portal for good, he will be captured by Prince Sindarian. What happens after that wasn't covered in the prophecy, but he doubts that whatever the ruler of the Unseelie realm has planned for him will be pleasant.
