The Wilde Trials

'Chloe Gatti will do whatever it takes to win her elite boarding school's annual competition, the Wilde Trials. In the two weeks leading up to graduation from Wilde Academy, a dozen seniors are chosen to compete in a series of seven ultimate physical and mental tests, and the winner will take home over half a million dollars--money that Chloe needs to help her sick sister. But the competition is fierce and includes her brooding ex-boyfriend, Hayes Stratford, whose brother was the only student to die during the trials a few years ago. When someone starts blackmailing Chloe during the competition, she's forced to strike a deal with Hayes--if he helps her discover who is sabotaging her, she'll help him solve the mystery his brother left behind.'
