Safe to say this was one of the most gripping, interesting books I have read in a while. The way the author reveals snippets of murderers life throughout the book keeps the book flowing well, and beginning with a chapter of the murderer immediately draws your attention. whilst reading the chapters from the main characters point of views it is easy to become invested in them, especially with the chapters jumping from past to present. this change in the time frame allows readers to discover how diverse Alison is as main character allowing the reader to understand her past. The way the book ended was perfect, I simply did not anticipate the plot twist at the end! I very much recommend this novel!!
