Three trilogies followed: "The Secret Circle" (1992), "The Forbidden Game" (1994) and "Dark Visions" (1995). The first installment of "Night World" series was published in 1996, followed by eight more over the next two years. 
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 Night of the Solstice" and "Heart of Valor" were also reissued in 2008. Three new "Vampire Diaries" installments were published in 2009 and 2010. 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.
The Originals (TV series)
In August 2017, it was announced that a spin-off focusing on Hope Mikaelson, the daughter of Klaus and Hayley, was in development. Julie Plec, co-creator of "The Vampire Diaries" and creator of "The Originals", wrote the script and is credited with creating the series. In January 2018, it was revealed that filming for the pilot would go into production in the second quarter of 2018. It was announced in March 2018 that the spin-off was in fact ordered to pilot, but instead of a traditional pilot, Plec would be delivering a fifteen-minute pilot presentation of the series to The CW. It was also announced that "The Vampire Diaries" veteran Matt Davis would star in the project along with Aria Shahghasemi, Quincy Fouse, Jenny Boyd, and Kaylee Bryant. Shahghasemi will debut in the fifth season of "The Originals" as Hope's friend Landon.
