So I'm horrible at summary's but the Geist of it is the story is about Rapunzel,Brave,Frozen, and httyd but it's not about the main characters it's about there parents and what there life was like as teenagers. So there is Arianna(Rapunzel's mom) Ean( Anna and Elsa's Dad) Elinor(Merida's mom) and Valka(Hiccups's mom) and there all siblings I know there different time periods and stuff but who cares artistic freedom and plus they all kinda look similar
