In Singapore and beyond, there has been a quickening of interest in the anticolonial and socialist struggle of the 50s and 60s after the publications of archival research by historian PJ Thum and of the Eisner-winning graphic novel The Art of Charlie Chan Hock Chye by Sonny Liew, among other works. The undisputed leader of this historical struggle was the student activist, trade unionist, and politician Lim Chin Siong (LCS), who organised the largest social movement in Singapore to fight for democracy, freedom, and justice. Although this movement ultimately failed, it opens a window into an alternative future for Singapore, Malaysia, and the rest of Asia—a window that creative writers with their imaginative powers can help us look at and through.

Deadline for submissions is 1 December 2023. There are also introductory material on Lim Chin Siong himself and the historical context he was in.
