The clever one - Helena Close

I've always been 'the clever one'. So clever that I got 10 As in my Junior Cert. So clever that everyone knows I'm destined for great things. But my family chooses to ignore how clever I am when I tell them that all this is going to end badly.
'This' being my sister Fiona's announcement that she is having a baby (father: Big; occupation: shady scumbag). At first, I swore I wouldn't help her. After all, if she wants to be a pramface, that's her problem. But I didn't realise how much I'd love baby Harvey, and want to do everything in my power to protect him.
Mam is doing her usual act of pretending everything's fine. My brother Cian is in a world of his own. My shiny happy best friend Mark thinks I should stay out of it.
But I can't. So I try to figure out a way to get Big out of our lives for good. And once my plan is in motion, I can't go back. No matter how much I sometimes want to.
