I love stories about sisters, whether it's drama, fantasy, humor, mystery, etc. The synopsis and first look are quite intriguing. The premise of sisters who don't really get along all that well, coming together to save one of them grabs at me. So does this line: "But soon, both sisters realize that finding her also means untangling the secrets that lead to the truth—about where they're hiding Autumn, and what Autumn has been hiding."
