First,
It's wonderful that you had such a successful start. I don't think most new authors are successful so early in their career.
Your experience with your second set of books is probably more common.
As to why some books take off and some books don't, that is a mystery.
Second,
You shouldn't refer to another author's work as "garbage". That's your opinion.
Others must think the work is good/great/worthwhile/valuable if they are willing to pay $2.99 for that author's short stories.
