Little Lies by Helena Hunting

My best friend's younger sister is the bane of my existence. And she just moved in.

The last time I saw her I broke her heart. Shattered it, actually. It had to be done. I'm the worst person she could end up with. I'll ruin her if given the chance. 

But she's not the meek girl I left behind. And she's making it impossible to avoid her. Her new favorite pastime is pushing every single one of my buttons.

When she shows up at a pool party wearing a small white bikini and flirts with my team-mates, I'm not sure I'll survive the year. Especially when she looks like every fantasy I've ever had. 

She's totally off-limits. Completely forbidden. The one woman I can't have. 

And the only woman I've ever wanted.
