The following is from The Wallstreet Journal:

On April 13, author Stephenie Meyer will publish the paperback edition of her best-selling sci-fi book “The Host.” Meyer, the author behind the “Twilight” series of books, will include in the coming version of “The Host” a never-before seen “bonus chapter.” “The Host,” Meyer’s first novel for adults, tells the story of body-snatching aliens who invade the earth. One of these extraterrestrials, who goes by the name Wanda, develops an unusual relationship with Melanie, the woman whose body she has taken over.
