Here's why:
* Nora's career struggles: While Nora takes a step towards addressing her fear of commitment and personal fulfillment, the story doesn't explicitly detail her career advancement or a complete resolution to her work-life imbalance.
* Charlie's past: Charlie still carries the weight of his past relationship and his fear of losing the person he loves.
* Their relationship: While Nora and Charlie begin to build a genuine connection, they haven't truly addressed the issue of distance, as Charlie is still living in New York.
Instead of a clean resolution, the ending of "Book Lovers" suggests a hopeful, but uncertain future. The focus is on the journey of self-discovery and the possibility of a new beginning for both Nora and Charlie, leaving the reader to imagine what lies ahead for them.
Ultimately, the book's ending reflects the complexities of love and relationships, leaving room for continued growth and change in their journey together.
