Million-selling young adult author Cassandra Clare has signed up for a new fantasy series.
Margaret K. McElderry Books, an imprint of Simon & Schuster Children's Publishing, announced Tuesday that Clare has agreed to a three-book deal for "The Dark Artifices," set in modern Los Angeles.
Financial terms weren't disclosed, but an official with knowledge of the negotiations told The Associated Press the deal was worth in the high seven figures. The official wasn't authorized to discuss the contract and asked not to be identified.
Clare, 38, is known for the series "The Mortal Instruments" and "The Infernal Devices." The first of "The Dark Artifices" books, currently untitled, will come out in 2015. According to a statement from the publisher, Clare, who placed her previous work in contemporary New York and Victorian England, will continue her tales of the Shadowhunters, a hybrid race "unseen but ever-present, our invisible protectors."
"The series follows Emma Carstairs, the fiercest warrior and most skilled young Shadowhunter since Jace Wayland, and Emma's sworn partner in arms, Julian Blackthorn," the statement reads. "Despite Emma's complicated feelings for Julian, the two must band together to investigate a demonic plot that stretches from the warlock-run nightclubs of the Sunset Strip to the enchanted sea that pounds the beaches of Santa Monica."
Clare said in a statement that she was sure readers would love both her new and her established characters.
"I know readers will come to love Emma, Mark, Cristina and Julian just as they have loved Jace, Clary, Will, Tessa and Jem," she said. "Readers have often asked what will happen in the Shadowhunter world after the events of the `Mortal Instruments' and this series will give them a chance to find out."
More than 6 million copies of Clare's novels have sold worldwide since she debuted five years ago with "City of Bones." The fifth of her "Mortal Instruments" series, "City of Lost Souls," comes out May 8.
Before "City of Bones," Clare was an author of fan fiction, for which writers make up new stories about popular literary characters and settings. Writing under the name Cassandra Claire, she published Harry Potter fan fiction on FanFiction.net in 2000-01. But after allegations that she had borrowed improperly from fantasy writer Pamela Dean, the website removed her work.
