Shaheen was diagnosed with depression at eighteen, after five years of already living with it. Touted to be the "bravest memoir" on depression, the book, according to Gurveen Chadha, Commissioning Editor at Penguin Random House India, is an "essential reading" for anyone trying to make sense of the mysterious and debilitating condition of depression.

"Her book is honest, all-consuming and so intimate, it's almost like taking a voyeuristic peek into her life... I am extremely proud to add Shaheen to the Penguin family and certain this book will make a monumental difference to our attitudes and perceptions towards mental health illnesses," said Chadha.
