Caleo and Percabeth they are just the perfect ships ever. I have been shipping Percabeth every since the Titan's Curse because it is so obvious like why can't you just admit it. Then there's Caleo Calypso and Leo they hated each other at first but then they didn't ha! It's sad though because no one finds Ogygia twice and Leo swore that he would and what if he dies what if Calypso dies what if okay I'm rambling but you guys should totally read the series (both of them so you would understand read PJO first)
