Rocks in the Belly [EPUB ebook] 

You’re eight years old. An only child. You love your parents, but you’re convinced you’re not enough for your mother because she fosters other people’s kids. You’ve learnt to cope, just about, with how this makes you feel — but then a boy called Robert arrives, and he and your Mum seem to connect in a way you never have. You hate him for it.
And her.
And one day you do something really bad to teach them both a lesson.
At twenty-eight, you return home to face your mother, who is now chronically ill. Despite the intervening years, you haven’t forgiven her – or yourself – for what happened. Ultimately, though, it’s her forgiveness you crave, even after all this time – because you need to know, finally, that you were enough for her.
