Iced

Miles Pussett is a former steeplechase jockey. Now he gets his adrenaline rush from riding down the Cresta Run, a three-quarter-mile Swiss ice chute, head first, reaching speeds of up to eighty miles per hour.
Finding himself in St Moritz during the same weekend as White Turf, when high-class horseracing takes place on the frozen lake, he gets talked into helping out with the horses. It is against his better judgement. Seven years before, Miles left horseracing behind and swore he would never return.
When he discovers something suspicious is going on in the races, something that may have a profound impact on his future life, Miles begins a search for answers. But someone is adamant to stop him - and they'll go to any lengths to do it . . .
