Erika Johansen’s futuristic dystopian fantasy, set in the 24th century following the collapse of the world order, is the ideal summer read – absorbing, detailed and with the ability to transport the reader to a different world. Emma Watson, who’s already signed on to play protagonist Kelsea Glynn, the 19-year-old rebellious Queen in the novel, has said she became obsessed with the book and couldn’t sleep for a week till she had finished it. If that isn’t recommendation enough, we don’t know what is.
