Awkward teenager Hugo Whittaker doesn't know a cross-trainer from an elliptical, but getting strong is the only way to fight off the bullies who won't leave him alone. Lauren Evans loves her job as a fitness instructor, and she wants to guide him. Unfortunately, Hugo paid for his gym membership by stealing his mother's credit card, and it doesn't take his mother long to track down her wayward son.

In a courtroom, shrewd barrister Allegra Whittaker is unstoppable, but when it comes to her son Hugo, she's afraid she's losing her touch. She reluctantly allows him to continue using the gym as long as she can keep an eye on him—and his undeniably intriguing instructor.

As each encounter leaves them wanting more, Lauren and Allegra learn love and happiness are right where they least expect it. There's just one little problem: Lauren has a huge secret she absolutely cannot tell anyone, and Allegra knows she's hiding something.
