OMG I CAN'T EVEN. JUST NO. WHY. WE HAVE A DAM PROBLEM 
 (view spoiler)[ PERCABETH! 
 How are they going to close the Doors of Death without someone sacrificing themselves on the other side. When Leo mentioned this I was like............NO NO NO! How do they all get out of this? (hide spoiler)] 
 Okay so to be more coherent, this book is my favourite because the Seven of the Prophecy have finally assembled! I love that they are all becoming friends and forming strong bonds. Jason and Percy can actually do some pretty cool things when the work together, I mean look at that epic hurricane. Annabeth proved once and for all that she is not only the cleverest child of Athena, the only one talented enough to find and outsmart her way to finish the Mark of Athena, but she is the leader of the Seven, especially when she puts Percy and Jason in their place and gets the head of the table. AND MOST IMPORTANTLY, WE FINALLY GET OUR PERCABETH REUNION. ALSO, PERCY SUMMONING THE WAVE THAT SAVED THE GIRLS IN CHARLESTON, THAT WAS SO COOL! Nico even said that Percy is the most powerful demigod he's ever met.
