I have no idea why I waited to read this book even if it is so different from the other series written by this author. I loved the characters so very much I especially loved Emilia and Wrath both were such interesting characters they also had great chemistry. What I loved about Emilia was her determination to find out why her sister was murdered and what led up to this happening to her. I loved the sheer amount of chemistry between Emilia and Wrath was amazing from the start looking forward to where it all goes from here. I loved the plot it starts with Emilia's everyday life to lead up to finding her sister's body so she sets out to find out the who and why she summons a demon named Wrath other things happen they are like oil and water but have great chemistry other things are found out looking forward to reading more soon.
