Well, Silver Skates is not based on real events. It's a work of imagination crafted by the author to take the readers on an exciting fictional journey.
One key element is the unexpected opportunity. The backup goalie gets a chance to play when no one really expected it. Another is their performance. They have to perform at a very high level to turn the situation around. Also, the team's reaction to them is important. If the team doesn't support the backup goalie, it's hard for the cinderella story to unfold.
A back up goalie cinderella story typically involves a goalie who is not expected to be the hero. They are usually on the bench, waiting for their chance. But then, fate intervenes. Maybe the starting goalie gets sick or is sent off. The backup steps into a high - pressure situation. And instead of crumbling, they rise to the occasion. Their performance can change the whole dynamic of the team. They might make a series of spectacular saves that boost the team's morale. This kind of story gives hope to all those who are in a backup or underdog position, showing that with the right opportunity and determination, they can achieve great things.
Friendship and rivalry. In many fanfictions, Bella has friends at the ice rink who support her, but she also has rivals. This creates a dynamic where she has to balance competition and camaraderie. For example, she might compete with another skater for a spot in a big competition while still being friends off the ice.
I'm afraid I can't say who the author is. You could ask at a local comic book store. They usually have a good knowledge of different graphic novels and their creators.
I'm not sure specifically as I haven't read it. But it might be about Karen's adventures on roller skates, perhaps her experiences in a roller skating rink, her interactions with other skaters, or her journey to improve her skating skills.
