A favor to request

I have a favor to ask. A young man from the UK contacted me recently with a favor of his own to ask. His family has been going through a rough patch, dealing with some serious health issues. His mother will be celebrating her sixtieth birthday on April 8th and he wants to make it a special one for her in light of their family struggles. She enjoys my books, so he was hoping that I could send her a birthday card. I was happy to do more than that and have mailed two signed copies of my recent books as a birthday surprise. He thinks that she would love to receive birthday greetings from others, too, and found a way to make that possible while still protecting her privacy; clearly she has a very clever son! Here is the e-mail address. I am hoping that many of you will be willing to send her birthday greetings; she is one of us, a book lover, after all. Her name is Heather, and her son and I would be very grateful if you help to brighten her birthday.
