Diver remembers everything about her past life. Being a student at the palace, her mother (the guard Shell), dying, and... Pearl.
But now she's been reborn (Or reHATCHED, haha). And she can't tell anyone. The enchantment that saved her won't let her. But now that she's Dolphin, she has a second chance.
She has to make sure it doesn't end like her first.
