Sure, it is. This book has the elements typically found in literary fiction like deep exploration of human emotions, sophisticated language, and a focus on character development.
I really liked 'The Lost Legends'. In this fanfiction, it explores what would happen if some of the Legends got separated during a time - jumping mishap. It dives deep into their individual strengths and how they manage to find their way back to each other, all while trying to fix the time - stream errors they accidentally caused.

The 'tomorrow and tomorrow and tomorrow short story' might have a theme related to hope or the lack thereof. If it focuses on multiple 'tomorrows', it could be showing how characters either look forward to the future with anticipation or are trapped in a cycle where each new day (tomorrow) is just like the last. Without reading it, it's hard to say for sure, but these are some common interpretations in literature related to the idea of successive days.
