This subject hovers over a writer with predestination in its wings.
The first book I published, The Battle of Chibi in 2010 occupied me through six proof versions. Eventually, I learned the value of editors and proofreaders. But "indie writers" all deal with questions about cost and struggle with cost-effectiveness.
