Hello Hello hello everyone, some VERY important Mortal Instruments news...
THERE ARE GOING TO BE SIX BOOKS!
For those of you who are sceptical about my sources, this information was found on Cassandra Clare's blog just in case you want to check it out :D
From Publisher's Weekly:
Simon & Schuster has signed books five and six in Cassandra Clare's bestselling YA series, The Mortal Instruments. S&S says there are more than three million copies of the series' three published titles in print. Clare launched The Mortal Instruments in 2007, with City of Bones, about a teenage demon slayer; City of Ashes and City of Glass followed. Book four, City of Fallen Angels, is scheduled for April 2011... The two new books under contract-City of Lost Souls and City of Heavenly Fire-are scheduled, respectively, for May 2012 and September 2013.
Clare will also be touring, in late August, to promote Clockwork Angel, which is the first title in the prequel series to The Mortal Instruments, The Infernal Devices. Film rights to The Mortal Instruments have been optioned by Unique Features.
So yes, in other words, City of Fallen Angels is not going to be the last book in the Mortal Instruments series. After it publishes next April, it will be followed by two more books: City of Lost Souls, and City of Heavenly Fire.
...so what does everyone think? Cassie Clare says that there will be a new villain for the next 3 books so no one has to worry about Johnathan coming back!
