Precap
Annabeth ! Percy! Nico! Bob is back !” I turned around and saw Bob running out of the cave. “Bob! ”Annabeth cried and the three of us ran to give him a hug. “ Are you alright ? ”Percy asked.
“Bob...saw the three of you leaving me...” He said with a worried look on his face .“ Bob , it’s alright. We are here now, of corse we won’t leave you ! It’s only an illusion. ” Annabeth exclaimed.
“Bob is happy to have you as my friend .” He said with a smile.
“Me too.” Annabeth said.

Percy’s POV
“Bob , do you know is there any more ways we can get back to the mortal world ? ” I asked.
“Hades said that he would open the door if the time has come...but..what door ? ”
“Bob also don’t know what on Hades Hades is talking!” He exclaimed.
(lol...kind of a tongue twister there)
“ I think we should stick to the plan and go to the doors of death...at least it still works, i guess. ” Annabeth said.
“There will be much more monsters to fight if we go there. You already know what happened last time we go there. I don’t want it to happen again.” Nico said.
“But there’s no other way ! ” Annabeth shouted. “ Um...guys? mabye we should stop arguing and start moving. ” I suggested. “Bob , can you lead us the way ? ” I asked.
“sure ! ”He said with a smile. “But watch out for monsters .” He added.

As we walked, i kept on thinking about the illusions i had in the cave. It’s over...its only an illusion.It won’t be true...I told myself. I also miss camp a lot . Staying in Tartarus it’s just...terrifying. Always fighting monsters and old enemies, i just missed the sunlight. I miss my friends. Jason, Piper, Frank , Leo , Hazel..... Leo would probably be saying his cheesy puns and annoying the campers now.That’s what he does...(#teamleo leo is hot stuffffff~)I remember all the quests we had been through togather.Those are real good times. I looked at Annabeth , she looks exhausted, but i’m happy that she’s my girlfriend. We’ve really been through a lot together.

Suddenly , a ghostly voice sneered.
" You've all passed my trial...  You shall pass..."
A ghostly figure appeared." Who in Hades are-" my voice was muffled by Annabeth.
" Lady Melinoe , " Annabeth spoke.
"This is your reward young heroes. " Melinoe said. 

She handed Nico a glass bottle , a piece of paper inside the bottle.
" Use it wisely... You only have one chance.... Once you arrive , the map will evaporate. When you leave the doors , it shall find a new location. This is a one way trip heroes. Good luck. " her ghostly voice gave me the shivers before she disappeared into smoke.

“Wait...What just happened ? ” I asked. It just happened so fast...well , first we wanted to go to the house of hades.Then suddenly a spooky ghost lady just appeared in front of us and told us that she got a map for us. What on earth is wrong with this universe ? Well...nevermind.I guess we just follow the map.
“Nico , where does the map lead us ?” I asked. “It leads to my father’s secret door and the door brings us back to the mortal world! I never knew that my father had a secret door...” Nico said with shock.
“Well...that's good news ! I hope there’s no monsters there.I’m tired of fighting. ” Annabeth said.
“Well then , what are we waiting for ? Lets go. ” I said.
“We should head north.” Nico said.
“Then north it is .”
