What's the Big Secret?

Eleven-year-old Aditya really wants to know.

Ever since Rhea Didi began getting brown paper packages, there's been something that no one is telling him. Mama turns red, Pa chokes on his coffee and Dadi has steam coming out of her ears! Thank goodness for his friends Naveen and Vinay-whom he can talk to.

But when Vinay brings an odd-looking napkin to school that soaks ink, Aditya is even more confused. Doesn't his sister use a microtip pen?
