Synopsis
All Liam ever wanted was to help me reach my full potential. And he always knew what was best. Until the day he pushed me far beyond my limits, and I walked out of our flat and away from our relationship to good.
Now, two years on, I am stronger, fitter, healthier than ever before. And then I see him – Liam – those green eyes, those stirring muscles. Something inside me flips. I want revenge, and I’m willing to do almost anything to get it.
I hold the power now.
It’s Liam’s turn to sweat.
