When Sylvia's equestrian plans are reined in after she's accused of dangerous riding, she realizes she's been ignoring an important personal decision.

Granted, there have been other distractions. She's been saddled with family secrets. Her relationship with Logan Losino has become utterly confusing. And sometimes the person who seems to understand her best is her former tormentor, Topaz.  

No wonder Sylvia wants to distract herself by galloping over dangerous obstacles on cross-country courses.

Until she can't.

And the clock is ticking. She's almost fifteen. It's time to start estrogen treatment. Or not.
