Adichie unveiled 'Notes on Grief' on her social media handles with news that it is already available to readers in the United Kingdom and the United States of America.

"It's profoundly bittersweet to see these lovely little books. I wish I had never had to write NOTES ON GRIEF and yet I am grateful to be able to honour my father, and my love for him, in this way. For grief is indeed about love; we who grieve are fortunate to have loved," Adichie wrote on Instagram.
