Shortlisted for the Waterstones Children's Book Prize, the Federation of Children's Book Groups Prize and longlisted for the 2015 Carnegie Medal, Kim Slater's outstanding debut, Smart, is moving and compelling novel with a loveable character at its heart.

'I found Jean's friend dead in the river. His name was Colin Kirk. He was a homeless man, but he still wanted to live.'

There's been a murder, but the police don't care. It was only a homeless old man after all.

Kieran cares. He's made a promise, and when you say something out loud, that means you're going to do it, for real. He's going to find out what really happened. To Colin. And to his grandma, who just stopped coming round one day. It's a good job Kieran's a master of observation, and knows all the detective tricks of the trade.

But being a detective is difficult when you're Kieran Woods. When you're amazing at drawing but terrible at fitting in. And when there are dangerous secrets everywhere, not just outside, but under your own roof.
