I'm not sure specifically as I haven't read this particular novel. It could be about the new experiences and adventures of twin siblings in their life, perhaps dealing with growing up, relationships, or achieving their dreams.
One possibility is that the twins are trying to break away from their old identities in their new life, but society or their family has certain expectations that create a conflict. For instance, if they come from a traditional family where twins are expected to be similar, but they want to be individual in their new life.
It could be very interesting. The fact that it's about twin siblings already makes it unique. Their new life might be filled with unexpected events and twists that keep the reader engaged.
Obviously, the twin siblings are the main characters. But there could also be other important characters like their parents who might play a role in their new life journey, either supporting or causing some conflicts.
