Soulmates (Heroes of Olympus AU)

What happens when at school all the Percy Jackson charachters have a tattoo in their wrist that resembles their soulmate? That is exactly what happens in this fanfic. When you turn 13 the tattoo appears. After you meet them more details appear to it. Once you are in love and have kissed them, your soulmates name will appear in small cursive beneath the tattoo. I do not own these charachters Uncle Rick does and I do not live on peoples sadness and I try not to leave to many cliffhangers.
