There's no way to tell for sure who Adrian is from just this title. He might be a local figure in a particular community where this 'presentacion' is taking place. Maybe he's someone known for his interesting stories or he could be a new face who has a very personal and secret story to share.
One main theme is race. Easy Rawlins, being an African - American in a certain time period, faces discrimination and has to navigate through a society that is often unfair towards him. This theme is explored through his various interactions and the cases he takes on.
Again, not knowing the details of this story, but generally, a person's true story can be interesting if it involves overcoming challenges. Maybe Doug Rawlins overcame some hardships in his life, like financial difficulties or health problems.
There might be, but I haven't heard any definite news about it. Sometimes publishers keep these things under wraps until closer to the release date. You could also follow the author's official social media accounts for updates.
It could be a collection of Debbi Rawlins' works that are in the genre of fantastic fiction. Maybe it includes stories with elements like magic, extraordinary characters, and unique settings.
