Books/Shows With a Strong Couple Bond Similar to that of Bella & Edward
The Outlander Series: (books/show) gives me the same vibes as the Twilight series. The bond between Claire & Jamie is as close as Bella & Edward's bond.
The "All Souls" Trilogy & Universe Series: (books/show) are worth reading/watching as well. The bond between Diana and Matthew is just as close as that of Bella/Edward and Claire/Jamie. And sometimes when reading the books I got chills because it had scenes that gave me Twilight vibes.
The Roswell TV Series: (1999–2002) is worth watching. The bond between Liz & Max is as strong as these others. The show is based on a book series, Roswell High, but I haven't read any of them, so I can't comment on them. There is also a reboot called, Roswell, New Mexico. It's okay . . . my heart belongs to the original.
