DIVERSITY IN ALL THAT'S MISSING

Like every writer, I am incredibly grateful for readers.  There is no better feeling than when a writer reads a review of her work in which a reader points out exactly a detail or theme or circumstance that the writer was hoping to achieve.  Of course, ultimately, the responsibility lies with the writer to create the world she envisions effectively enough for the reader to see it as the writer imagined  it.  Nevertheless, nothing feels better than positive confirmation that a reader "got" what you were trying to do.
When I wrote ALL THAT'S MISSING, one of my goals was for diversity to be a given in the lives of the protagonist and his contemporaries.  This reader’s words from a Goodreads review give me permission to believe I may have succeeded. 
“Read-alike to "Higher Power of Lucky" in that it's about a boy's search for a family as his sole-provider grandfather sinks into dementia. I liked that some characters were African-American, but it was such not a big deal that it took a while to figure out.”  Thank you, dear reader!
