Five novels “Twilight”, published between 2005 and 2008, tell the story of a teenager who fell in love with a vampire.
Fans of “Twilight” speculate about the completion date and eventual release since.
In addition to the countdown on the Meyer website, Fickle Fish Films, an independent production company founded by Meyer, focuses on converting books into films, short videos of starred skies and the words “5 days.”
On Thursday, another tweeted – “4 days” – prompted Twitter users to comment that they hoped the upcoming announcement would be about “Midnight Sun.”
CNN has contacted Fickle Fish Films and publishers Meyer, Little, Brown, and to provide comments.
Others on social media speculate the countdown might lead to a sequel to “The Host,” a book about parasitic aliens published by Meyer in 2008, which was turned into a film starring Saoirse Ronan in 2013.
But no matter what happens, fans just need to hold back their excitement until Monday to find out.
