Padme would most likely have an immediate emotional response. Tears might well up in her eyes as she sees Anakin burned. She would be in a state of disbelief at first, not wanting to accept that this has happened to him. But then, her natural instinct to care for him would kick in. She would use her influence to get the best medical care available, and she would stay by his side throughout his recovery, constantly reassuring him that he will be okay, even if she's not entirely sure herself.
Besides Padme, Anakin is a key character. Their love story is a big part of the Star Wars lore. Additionally, there could be characters from Padme's home planet who play important roles, like her family members or advisers. They might influence her decisions and actions throughout the novel. Also, some Jedi might be involved as they are often intertwined with the political and personal affairs in the Star Wars universe.
