Gunner - Nicola Jane - Bog

Ava
Loving Gunner came easy. It crept up on me suddenly, after years of living alongside him in The eagles MC. Getting him to love me back was the hard part.
Being the club princess and sister to the President makes my dating life almost impossible. Add the fact that Gunner is the Vice President and it's basically out of the question.
When Gunner decides to join the Army, leaving me and the club behind, I accept it. It's a shock to us both when we spend the night together before he leaves, but when he practically runs out on me the following day, I take the hint. He's not interested in anything serious.
Realising that Gunner is not my one true love, I throw myself into university, getting my nursing degree and becoming a better version of the mess he left behind.
So, when he returns years later, why does my heart want him all over again?

Loving Ava came easy. It was all the other stuff that made it complicated. I'd never disrespect my President by going there with his younger sister. She's completely off limits, so I ignore the obvious crush she has on me.
I decide to join the Army, but I can't leave without one night with her. Waking up the next morning and seeing the hope in her eyes kills me. And so, I break her heart and leave, vowing to never go near her again.
