Indie book publisher Author Solutions has solidified a $1 million development fund to finance screenplays adapted from books written by its stable of self-published writers, who account for more than 145,000 titles. The publisher, which has a first-look deal with Principal Entertainment, will run the fund out of its newly formed production shingle FuseFrame that is being overseen by Author Solutions’ film and new-media unit boss Marcus Chait. The first property in the fund is A Game Of Hide And Seek, by Irene Farrimond. John Swetnam is adapting the book, a thriller about a group of teens vacationing in a remote mountain resort who must rescue their parents after they are taken hostage by a band of criminals. Chait is producing with Principal’s Danny Sherman; Principal’s Jen Weinbaum is co-producing.
