So it wasn’t fair - or possible - for Allie to compete any longer against her former peers. Her body could out-sprint, out-jump, and endure far more than anyone else. But all that was behind her now. Allie realized that this whole time she’d been chasing the rewards rather than savoring the journey.

The girl placed a hand on her hip, giving him a flirty smile. “What do you think?” she asked, her voice huskier and more confident than it had been before...
