The book alternates between past (Eve) and present (Charlie) for each chapter. For the first half of the book, the past is way more interesting than the present and then somewhere along the middle, the past and present merge, but the chapters still alternate between perspectives which was really nice. There was some awful language in the book, but it wasn't frequent, thankfully! The past and present had a lovely symmetry that bordered on obvious and convenient. Really liked it, though. Would read this author again.
