Ok, so I emailed PB, and this was his reply-

Dear Emily:

Apologies if this reply has taken a while to get to you. The security systems we have to deal with are rather rigorous, to say the least.
Also, we are dismayed at how many of te read Mr. Bosch's fifth book, te HAVE TO STOP THIS. We urge te all to stay away. Please. For your own good and safety.
Unfortunately Mr. Bosch has tasked me with running security clearances and background checks on all the emails. I've decided to just reply to them instead. Don't feel too badly, though. There's a mountain of Cioccolato and carrots waiting for me...
