In a pre-emptive move, Mandalay Pictures has nabbed bigscreen rights to the just-published young adult novel Firelight. Supernatural tale, the first in a three-book series, was penned by bestselling author Sophie Jordan, aka Sharie Kohler. The story follows twin teenage sisters, the descendants of dragons who live in secret with their endangered pride. When their mother learns that the pride has a dark plan for one of the girls who possesses the rare talent of fire breathing, she spirits the twins away to live a normal life among humans. The Harper Teen book was one of the five selected by the YA Editor’s Buzz Panel at Book Expo America in May. The pre-emptive move is the latest for Mandalay, which recently optioned the bestseller “Horns” by Joe Hill, the soon-to-be-published “Machine Man” by Max Barry and “Lonely Hearts Club” by Elizabeth Eulberg.
