As of my knowledge cutoff date in 2023, there are no widely recognized authors by the name Robin Lefler. However, Robin Lefler is a fictional character in the "Star Trek" universe. She appeared in the "Star Trek: The Next Generation" television series. Robin Lefler was portrayed by actress Ashley Judd and is known for being a Starfleet officer serving aboard the USS Enterprise-D. Her character was a human engineer known for her precocious nature and for formulating a set of personal guidelines known as "Lefler's Laws." If there is an author named Robin Lefler who has gained notoriety after my knowledge cutoff date or if you're seeking information on a lesser-known or emerging author by that name, I would not have that information available.
