She said goodbye to The Hills
but Lauren Conrad
is still a fan favorite: Her debut novel, L.A. Candy
, has topped the New York Times
Best Seller list two weeks in a row.
"If someone said to me five years ago when this all started that I would one day make the New York Times
Best Seller list I wouldn't have believed it," Conrad tells PEOPLE exclusively. "I am so honored that it is now a reality."
The novel, loosely based on Conrad's own life, follows
of Jane Roberts, a 19-year-old girl who moves to Hollywood and ends up as the star of her own reality show.
Although Conrad is used to the spotlight, she's still in awe over her literary accomplishment, "It was such a compliment to be included in something with such established names."
, which hit shelves June 16, is the first in a three-book deal for the reality TV star.
