Random House (US) The Sending is the seventh novel in the Obernewtyn Chronicles by Australian author Isobelle Carmody, and is the penultimate book in the series.
It was originally intended to be the final book, but this was changed to allow Carmody to elaborate plot strands without it becoming too long.
The book follows the journey of Elspeth as she is finally called to set out on her fated quest to destroy the computermachines before they unleash a second apocalypse.
Carmody stated that the reason behind this decision was that the one volume was far too long, and such a split allowed her to elaborate on plot strands she had had to cut down.
To toxic Blacklands to find a pack of mutant human-hating wolves, for only they can lead her to the forgotten Beforetime city which haunts her dreams.
