Chapter1

"Hey Nico, are you friends with Frank?" Hazel asked Nico.

"Uh, no. Why...oh, gods, did you talk to Jason?!" Nico asked.

"No...why?" Hazel asked.

"Nothing. Why do you want to know, though?" Nico said, changing the subject.

Hazel sighed. "Nico, please don't freak out."

"Why?" Nico asked.

"Nico, me and Frank are getting married!" Hazel exclaimed.

Nico just starred back at her for a couple of minutes.

"Nico, are you okay?" Hazel asked. Her question seemed to snap him out of his trance.

"WHERE THE HADES IS HE?" Nico yelled. He twisted his body around and looked for Frank.

"Nico, don't hurt him." Hazel pleaded.

"Found him." Nico stated, clearly ignoring Hazel. He started to stomp over to where Frank stood. Hazel followed and tried to stop him.

Frank was talking to Percy Jackson, possibly telling him the news.

"Frank Zhang!" Nico yelled. Frank jumped and turned around.

"Nico, calm down." Percy said when he saw how mad Nico was.

"Don't tell me to calm down, Jackson, your not part of this!" Nico snarled. He pulled out his sword and pointed it at Frank.

"Dude, what's wrong?" Frank asked with his hands up in surrender.

"Why are you marring my SISTER?" Nico yelled. Some people turned around and looked. They were in the middle of Camp Jupiter. Reyna, the leader, came over.

"What's going on?" she asked.

"Nico's trying to kill Frank." Percy said.

"What?!" Reyna asked.

"Shut up Percy! I'm not trying to kill him, I am killing him."Nico said as he started to get closer to Frank with his sword in reaching distance. Frank backed up.

"Why is he doing this?" Reyna asked Hazel.

"Frank and I are getting married!" Hazel said.

"Congrad's!" Reyna said.

"No, not congrad's." Nico said.

"Nico, stop!" Hazel said. "We're getting married whether you like it or not!"

Nico turned around and faced Hazel. "Fine, I will be at your wedding." Then he faced Frank. "I'm watching you." Then he shadow-traveled away.

Hazel, Piper, Annabeth, and Drew went to pick out Hazel's dress. While they did that Nico was forced (by Hazel) to go with Frank, Percy, Jason, and Leo and get tuxes. All were getting their own except for Nico who sat in a corner and slept.

The girls were having fun picking out Hazel's dress and the bridesmaid dresses. They soon found Hazel a long, white dress and purple dresses for the others. Then they went and ate lunch.

Everybody was at the ceremony, which was at Camp Jupiter. Since the gods didn't show up Nico walked Hazel down. He said he did it to make her happy. That's it because he still wanted to kill Frank. When they got to Frank Nico glared at him and mouthed "This fight isn't over." then went back to his seat. The wedding went as planned with no objections.

At the part afterwards Nico did all he could do to get between Hazel and Frank. Hazel called him "selfish" as a joke but he didn't care. Soon he warmed up to the idea of having Frank as a brother-in-law. but just a brother-in-law.
