I've just received the book Soul Survivors from its author Charlotte Rush-Bailey, who was a participant in The Tribes of Rajasthan & Gujarat Photo~Expedition, and it's certainly a wonderful addition to anyone's travel book collection.
It's essentially a tribute to the people of the Sahel, and focuses on Niger which Charlotte visited in the fall of 2005, amidst a food crisis that had enveloped that nation. Despite the food shortages, Charlotte marvels at how she was welcomed with generous hospitality everywhere she went. The book is full of lovely photographs; many of which are portraits, processed in the photographer-author's signature style.
Published and available through Blurb, the link above provides a preview of some of the book's pages. My favorite photograph of the book is the 5th on the preview strip, which is of a camel caravan. Just a perfect composition.
Charlotte Rush-Bailey's website has more of her photography.
