I'm still working on my latest book and I really like how it's going. I hope I can share it with you soon. But I'm glad to see other people are writing books that involve braces too, and a new one just came out: F.N.Brown's The Illumination of Frances Harmon, which has a nice site and which you can get on Kindle at the American Amazon, or Amazon in the UK.
I've just read the sample text at Amazon and this sounds a lot different from what I have been doing, but I'm sure some of my readers will be interested in this too.
And what a great idea to have that book trailer!
I haven't come across any other new books in which braces play a big role recently, but I'm always looking!
