Book excerpt: There are two things you need to know about me. The first is that I remember life by what I was wearing. The second is that I think too much. It's the early 1990s and all Gemma can think about is looking perfect for her first school formal. Gemma's brother Billy - New York's up and coming hair and make-up artist - has made her the ultimate promise: he's returning home especially to 'create magic' on her and two friends for their end-of-year formal. Gemma's best friend, Andrea, is convinced it'll be their moment to shine; Gemma hopes it's the night Ralph will finally notice her. But when Billy arrives home from New York, Gemma's life becomes complicated. Her family's been keeping secrets; friendships are forged and broken; and suddenly the length of her formal dress is the least of her worries. Set in a time of uncertainty and fear, The Things We Promise is a beautifully told novel that sings with emotion, humour and heartbreak.
