The 26-year-old Dunham, who received Emmy nominations as producer, director, writer and actor for the HBO comedy, has an agreement for the essay collection "Not That Kind of Girl: A Young Woman Tells You What She's Learned."
"In the tradition of Helen Gurley Brown, David Sedaris and Nora Ephron, Dunham's book will offer frank and funny advice on everything from sex to eating to traveling to work," Random House said in an announcement Monday. Dunham said in statement that she was eager "to produce the most thoughtful and personal book" she could.
Random House spokeswoman Theresa Zoro said that no publication date has been set.
Numerous publishers bid for the book. Random House declined to offer financial details, but several competitors have said bidding exceeded $3.5 million.
