Jungle Horses by Scott Adlerberg focuses on a London man, who after falling into debt with the wrong people, is forced on a trip to a Caribbean island to study a mysterious breed of horses (available August 19, 2014).
The horses that Arthur saw in his dreams were always running through tropical terrain. The land was green and the sky deep blue, but this was not the African farm where he'd once bred racing horses. These were not those sleek thoroughbreds nor were they tame farm horses burdened by saddle, stirrup, and bit. The horses ran through a lush place, and despite the denseness of the terrain they seemed to run with complete abandon, never stumbling as they tore through bush. They were jungle horses, immense yet graceful, and somehow he knew as one knows in dreams that none of these majestic creatures had ever been mounted by a man. How different they were from the horses he'd ridden in his life, and how different too from the London ponies he would bet day after day. They were unique, he would think in his dreams, and the vision of their bright green jungle would fade, the beautiful horses would disappear, and he would awaken in the hard double bed with the grayness of the ceiling above him.
