In 1998, Smith began a decade-long hiatus from writing, returning in 2008 with a new website and a series of new short stories. "The Vampire Diaries" series was reissued in 2007, followed by reprintings of "The Secret Circle" trilogy and "Night World" series in 2008–2009.

The series was later adapted into a TV series ("The Vampire Diaries") in 2009, as well as "The Secret Circle", which became a TV series of the same name in 2011.
Kevin Williamson (screenwriter)
Williamson developed a new TV series for The CW entitled "The Vampire Diaries", which was adapted from a novel series of the same name by L.J. Smith. The series follows the life of Elena Gilbert (Nina Dobrev), who falls in love with vampire Stefan Salvatore (Paul Wesley), and soon finds herself caught in a love triangle between Stefan and his older brother, Damon (Ian Somerhalder), while the brothers are also being haunted by the past they've had with Katherine Pierce (also played by Dobrev). The series also focuses on the lives of Elena's friends and other inhabitants of the fictional town of Mystic Falls, Virginia. "The Vampire Diaries" premiered on September 10, 2009, and has become a domestic and international hit.
