Schnackie if you re prepared for a long wait for a reply you can write a letter. I oversee the Fanmail sent to my son which is about 95% online via email.
Sometimes children write to him via his literary agent or publisher and by the time they get round to passing it on to him by hand or sending it to him sometimes many months have passed. I think it is so sad because children want a quick reply and 4 months later or more they have lost all the excitement. By email they get an immediate automatic reply saying their email has been received and will be replied to as soon as possible.
I oversee them in case a child needs something for a school project and that email is pushed to the front. My son then replies quickly to them.
I suggest if you go down the email route you put the author’s name in google plus contact details with a question mark. Or go on their Facebook website and ask for it there.
Hope that helps.
