Sophie would definitely be one of the main characters. Since she's at the center of a lot of things in the 'Keeper of the Lost Cities' series, she'd be actively texting to keep in touch with her friends and allies. Fitz is also likely, as he's often involved in the important events and is close to Sophie. Keefe too, as he's a bit of a wild card and his texts could be full of his usual antics and important information at the same time.
There may also be some antagonists or characters that create obstacles for Tam. These characters add conflict to the story, which makes it more interesting as Tam has to overcome the challenges they present.
Well, it might be about the characters in the 'Keeper of the Lost Cities' using texting to communicate. Maybe they text to share secrets about the lost cities, or to plan their adventures. For example, Sophie could text Fitz about a new discovery she made in one of the hidden places in the lost cities.
I think Wylie could be one. He has so much potential but often gets overshadowed by the main characters. In fan fiction, his relationship with other characters, like his family ties, could be explored more, and he could be given his own adventures that showcase his unique skills and personality.
One idea could be exploring the backstory of a minor character in more depth. For example, the character's family history and how it might be related to the overall mystery in the Keeper of the Lost Cities world.
Well, in the 'Keeper of the Lost Cities Fitz' short story, Fitz is often depicted as a complex character. He has unique abilities that set him apart in the Lost Cities world.

Fitz is interesting because of his relationships. His bond with Sophie, for instance, is full of ups and downs. They have a connection that is both strong and fragile, and this dynamic between them adds a lot of intrigue to the story. Also, his interactions with other friends and foes in the Lost Cities keep the story engaging.
The interactions between Tam and his friends are quite engaging. They often face challenges together, and seeing how they support each other in the short story is heartwarming. For example, when Tam is in a difficult situation, his friends don't hesitate to come to his aid.
Without having read 'The Secret Keeper Novel', it's only speculation about the main characters. The secret keeper is most likely the main focus. There might be a love interest who is either in on the secret or unknowingly affected by it. There could also be a mentor - like figure who either helps the secret keeper protect the secret or tries to persuade them to do the right thing regarding the secret. There may be other characters that add depth to the story, such as neighbors or colleagues who might notice something strange about the secret keeper's behavior due to the secret.
I don't know for sure, but I assume the dragon keeper is one of the main characters. There might also be the dragons themselves as important characters, each with their own personalities and abilities.
