I liked the premise of this book but I must admit only a couple of chapters in I was doubting whether I would spend the whole read asking awkward questions of the author, mainly ones like ‘How on earth…?’ or the main question ‘But….?’.  Having said that, I liked the characters, Oona and her Mum in particular, so I bravely soldiered on.  Things began to fall into place and a vague sense of logic was resumed.  I was having more moments of ‘oh, that’s clever’ and less questions.The time travel aspect is not explained or deliberated over which made the book light and fun to read while still keeping some intrigue. I recommend it for the characters and the clever idea of the book which was well written and full of heart.
