Who is Dr. Lush Gjergji from The Missionary Position: Mother Teresa in Theory and Practice and what is their importance?

Dr. Lush Gjergji, an Albanian Catholic, is one of about twenty authors whose books on Mother Teresa are found by Hitchens in his search of the electronic index at the Library of Congress. All these books praise Mother Teresa, but the one that Hitchens uses most to describe her early life and to show how loving these authors are toward her is Dr. Gjergji's book, which Hitchens calls the most neutral one among them. Even so, Hitchens describes the book, called Mother Teresa: Her Life, Her Works, as a "sort of devotional pamphlet in the guise of a biography."
