Everything was going so well. Aelin and Rowan were ruling Terrasen. Aedion and Lysandra are married. Nesryn and Sartaq were visiting. Manon ruled the witches, and Dorian was safe in Adarlan. Chaol was hand of the king, living with Yrene and their son. Of course Evangeline was thriving as a Lady of Arran. And of course Erawan and Maeve were gone. They were content to sit back and relax. Elide and Lorcan were getting married, gathering the old gang back together. And then everything changes when Aelin, Elide, Nesryn, Evangeline, Yrene, Lorcan and Fenrys disappear.

Percy met his uncle a year ago. Right before the whole kidnapping. Percy's Uncle is billionaire Tony Stark. Now, Percy and Annabeth are looking for a little bit of relaxation. And so they decide to stay with Percy's uncle for a bit. No problem? Except the fact the Avengers don't know Percy is a demigod. And the secret his uncle is trying to hide from them. What lengths will Percy go to to uncover the truth? What could go wrong?

The Avengers were eating breakfast, enjoying the quiet after Ultron. And then the onyx haired woman landed in the middle of their table, along with six others. The Avengers don't know what to do. So they do what humans do naturally. Lock up the things they don't understand. The next problem is hiding the strangers from Tony's nephew and his nephew's girlfriend who is terrifyingly smart.

When a new threat arises will they be able to join forces? Will Lorcan's grumpy personality scare them away? Can the Demigods focus long enough to survive? Will Tony try flirting with any of the people and Fae from Erilea? All of these pressing questions will be answered.
