Spanning from the early 1990s to 2017, The Tonic is an emotive and heart-wrenching tale of an unlikely friendship between Masher and Raem, two young misfits. Through their eyes, the reader sees the impacts of the Bombay riots which connect them later in life to a media tycoon and atheist, who has genocidal plans for the religious. The two tales separated by decades slowly begin to converge to form a deadly truth that binds them all together.
