If it came down to a single book, a single book that transformed my reading experience, I'd pick Anita Desai's riveting 'The Village by the Sea.'
Many years ago, this book did it for me. When I spotted the book in the Page One bookstore at Vivocity, I was tempted to look for the buyer to congratulate him/her on their excellent taste.
There were two copies. I bought one. This year, Aneesha gets it as her Christmas gift. It might not change everything for her instantly but I know someday, she'll have to thank Anita Desai for it. Should this form of communication still exist, perhaps this note might end up being that useful reminder.
