All Books are second hand

Nerve - Rob Finn was a bit of a a struggling young jockey in a family of accomplished musicians, a man in love with a beautiful woman who wouldn't have him -- he suddenly looked like a rider who had lost his nerve. Could it be, though, that the horses were unusually sluggish, and that there was something more sinister attempting to sabotage him...?
Smokescreen - Edward Lincoln has scaled the Himalayas, survived car chases and defeated scores of assassins. As a movie action man he's even suffered stoically at the hands of sadistic directors.

After finishing his latest film, he visits South Africa to discover why a dying friend's horses are suddenly failing on the race track. Lincoln's attempt to help a friend soon puts him in harm's way. From a nearly fatal interview to a dangerous accident in a gold mine, it seems only luck is keeping him alive.
