On the hunt for MG and YA mysteries...
I often think of going back to Roald Dahl, to books I haven't read. He is quite popular in India.
I grew up loving his books. A hardcover was fairly expensive (relative to the States today) when I was young, and his books were always my 'big' birthday present :-)
I loved Roald Dahl's books and remember saving up money as a kid, so I could go visit the local bookstore and buy them.
I'm re-reading some--they're still great :-)
