Hard to say for sure. It could be inspired by real-life experiences but transformed and dramatized for entertainment purposes. Not everything presented might be 100% factual.
River Phoenix was a very talented actor. Axel Vendel might be someone related to documenting or researching his full story. River's acting in movies like 'My Own Private Idaho' was remarkable. His life was cut short tragically. He was part of a family of performers and had a unique charm on screen. His early start in the entertainment industry led to a meteoric rise. However, his struggle with substance abuse ultimately led to his untimely death, leaving behind a legacy of great performances and a reminder of the perils of the Hollywood lifestyle.

It's possible that there is a character who is in a state of transition or change. This character might be the central figure in the 'Here I Am Novel'. They could be facing challenges in their life, such as a career change, a move to a new place, or a shift in relationships, and through these experiences, they are evolving and coming into their own, which ties in with the title.
It might be about presence. It could be exploring the idea of being present in a particular situation, whether it's in a relationship, a community, or just in one's own life. Maybe the characters in the novel are learning to be more present and this is what the title is alluding to.
