Hello there!! Everything is great over here in Walker world, I'm just working on Regali (book 4).
In between that though I've had the opportunity to check out Chameleon by Kathy Stewart.
If you're interested in a thoroughly researched page turner set in South Africa during the two world wars this is the book for you.
Here are what others are saying about it - http://www.amazon.com/Chameleon-Kathy-Stewart-ebook/product-reviews/B00A823UYS/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1
