I received my books today! :)
If you are interested in buying a signed copy of Hidden Threat, Slave, or Behind Closed Doors, leave a comment below with your e-mail address and I will contact you with the details. You would have to pay for the cost of the book, any shipping and packing costs, and then any paypal fee involved. I've never done this before. If there's enough interest, I'll continue to offer it whenver I have physical copies of my books in stock.
