I'm not sure. It depends on various factors and the source of the story. Sometimes it could be based on real events with some fictional elements added.
Honestly, I don't know if Lola Igna is a true story. There could be elements of truth mixed with fiction. Maybe it's inspired by real-life events but exaggerated for entertainment purposes.
I'm not sure specifically what 'lola novel book' is about as the name is rather general. It could be a novel about a character named Lola, perhaps her adventures, relationships or personal growth.
