I've picked all of these for different reasons; nostalgia, intrigue, humour, loveliness, creepiness, and one of these is actually the first couple of sentences as I just couldn't resist the hilarity of it. I'm not going to explain these or give you any more plot information as I think that the sentences speak for themselves and will hopefully intrigue you enough to pick up the book. So let's get into it...

"The first thing you find out when yer dog learns to talk is that dogs don't got nothing much to say about anything.
'Need a poo, Todd'" - The Knife of Never Letting Go by Patrick Ness.
"In the golden half-light of a midsummer's evening, the sort where any kind of magic can occur, and often does, in the midst of a party held in a wild and rambling garden, stood Pierre, teetering on highly unsuitable heels, surrounded by a symphony of overripe roses." - The Man with the Dancing Eyes by Sophie Dahl
"No one could say it was my choice to kill the twins, any more than it was my decision to bring them into the world." - The Dumb House by John Burnside.
