This phrase denotes a particular literary work that follows an initial, and often successful, novel featuring sibling characters. It is, essentially, the subsequent installment in a series centered around a family, with “sister” serving as a focal point. An example would be a novel that builds upon the narrative established in its predecessor, further developing the characters and exploring new plot lines while maintaining the familial theme.
Continuations of this nature are significant because they offer readers further engagement with beloved characters and expanded understanding of the previously established world. They provide opportunities to deepen relationships, explore unresolved conflicts, and introduce new perspectives within the existing narrative framework. Historically, serialized novels and multi-volume stories have enjoyed considerable popularity, driven by reader demand for sustained connection with fictional worlds and personalities.
