My long lost family/ Meliodas x reader/

(Y/n) is known as the eighth sin/ the Phoenix sins of rebirth and death.
After being torn away from her lover and the other sins, she sets herself on a quest to find them and bring them back together. During the years of solitude, she meets a little wolf cub who was hurt in a fight and heals her to full health. Ever since that day Geringale never left her side.
(Y/n) was born as a demon and a goddess, but got cast away from helping Meliodas and the others during the first holy war.
After a few years of searching, (Y/n) stumbles across a strange looking tavern, but with a familiar face in it.
A/n: This takes place a few days before Meliodas meets Elizabeth.
This is my first book and my grandma said to me
"New book, new adventure"
So I guess this is my first adventure.
I do not own the characters in the seven deadly sins
