LUNA: The Invisible Princess (Book 1) (English Version)

(English Version)
~~~

Her name is Luna. No one sees her except her twin sister. She envies her twin sister's life, although their parents never failed to tell her they love her even though they can't see her. Luna was in total darkness while her twin sister had the life she wanted to be. She wanted to be as happy as her twin sister, but how? She's invisible. The thought depresses her so much that it leads her to run away from the palace.

However, she accidentally fell into the portal, going to other dimensions that she didn't know existed. She doesn't know how to come back to her world. Later on, she accepts her fate and lives a life of being in different places, especially when something strange happens to her. She misses her family so much, but how could she come back? Will she remain forever in different dimensions? Will she survive alone?

Unexpectedly, a twist happened. Leena, twin sister of Luna, fell into the portal too when she learned that her twin sister accidentally fell into the mysterious portal tree. However, fate never let them see each other and she's gone to a different dimension. The twins face a different path. Will Leena find Luna? Will they reunite again?
