Lucas och hans syster Mercy vill väl när de tar med lillebror Jed och glömske farfar Norman ut för en heldag i London. De ska ju bara åka tio stationer med tunnelbanan - vad skulle egentligen kunna hända?
Jenny Valentine moved house every two years when she was growing up. She has just moved house again, probably not for the last time. She worked in a wholefood shop in Primrose Hill for fifteen years where she met many extraordinary people and sold more organic loaves than there are words in her first novel. She has also worked as a teaching assistant and a jewellery maker. She studied English Literature at Goldsmiths College, which almost put her off reading but not quite. Jenny is married to a singer/songwriter and has two children.
In 2007, Jenny won the Guardian Prize for Children's Fiction with her debut novel FINDING VIOLET PARK.
