Rowan Rossler serves up more sexy drama in The Challenger, a fiery sports romance saga of strokes and seduction where the only rule of play is when love meets its match, it's game on. Chavez Delgado should come with a warning label: Caution explosive material. A volatile tennis prodigy once tipped to win majors, this wildly unpredictable fan favorite never quite lived up to all the hype. So when he leaves the tennis tour without explanation during the best year of his career, no one expects him to grind out a comeback on the second-tier Challenger circuit eight months later. I've met my share of hot messes. Call it collateral damage of being Flynn Dryden-motivational guru to struggling millennials. But I have never met anyone like Chavez. Young and yummy with complications written all over him, he pushes all my right buttons. But when he asks me to join him on tour as his mental fitness coach, I say yes for all the wrong reasons. As it turns out, we both have unresolved issues. And playing a game called love puts us both in danger of getting burned.
