After their classes:

                "Hey! Where's Rose?" James asks, breathing in and out rapidly, it obvious that he had been running.

               "She's going to the school library to borrow books for her homework." Albus answers calmly.

               "Speaking of homework, I really need Rose help for it."

                "Not smart enough to do your own homework, huh?" Albus smirks, mimicking his brother's.

                "Not enough but at least smarter than you." James replied.

                 Albus is about to fire back, but then Rose, out of nowhere, interrupts their fight, "Guys! You won't believe what I found here!"

                "What?" they both ask at the same time, then glare at each other.

               "I can't believe that I'm related to you! You are like  a total Slytherin! Guess that is why Dad named you after Snape!" James mutters

               "Hey! And pay some respect for him, he's Professor Snape! Beside, as I said earlier, he' s not BAD!"  Albus particularly screams out the word.

               Rose sighs, "Looks like we got sibling fight again. You two are just.....unbelievable! But hey look at this!"

               The three of them sit on the bench and begin reading.

              "So what?"

              "Do you know what this mean?" Rose asks, a trace of pure excitement in her voice.

              They both shake their head.

              "It's means that there are a similar group like us called "the demigods", who are like the muggle-borns here. Half that and this...."

             "The what?" James and Albus both interrupt her, "dim-gone? What?"

             "Demigod" Rose corrects then continue. "They live far away. They are the children of the "Greek gods" whoever those people are, they seem to be very powerful. They control almost everything, the fate of the world, the seasons,... but they can't control our lands, the lands where the wizards and witches rule."

            "This book is telling us how we came to be, to have magics. The history that nobody know, no Professors nor witches or wizards until now, the history that remains a mystery until today, and we shall learn it." The three look at each other, at that moment, they know that their real journey begins and they will do everything they can to reach the end.
