Puthaiyal Theevu - Pa. Raaghavan.
It's a children's book, actually. Pa. Ra. says that this is one of the stories that he wrote very early in his career and is still very close to his heart. He admits that there are some stuffs that could have been improved in this, but decided not to touch it since he treats this as a memory.
It's a very small book, takes you into an adventure along with Balu, KudumiNathan and DelhiBabu into the "Pandri Theevu". I liked that the author had managed to keep what the treasure is as a suspense until the last few pages of the book! Straightforward kids level thinking and implementation. As he said himself, there are places where a small rework could have improved this novella much better. I still loved this book as this has finally broken my reading block!
