Author is famously guarded, so why agree to interviews?

Jumping on the publicity bandwagon must always feel like a real dilemma for JK Rowling.

The Harry Potter author has been all over the place recently thanks to the release of her new adult fiction novel, The Casual Vacancy.

Interviewers are nosy by nature and will expect her to provide titbits about her private life in return for her book getting plenty of lucrative column inches.

But Rowling has been famously guarded in the past, so I wonder how she squares the process of trading personal information for public consumption?

In reality, her new book was always bound to fly off the shelves without her needing to do a single interview, so it’s surprising that she didn’t stick to her guns and refuse all requests for a chat.
