This was such a good ending to a series. It has so many unexpected twists and i really adored it. I loved the ending of the triangle. I loved learning the truth about Jem and seeing if that will be shown in heavenly fire. I love the development of all the realtionships esp. sophia and gideoan which was such a sweet love story. I also loved the focus on the letters that were given to this book. This was one of the best conclusions that i have read and still one of the strongest triangles in YA that being tessa, jem and will. I thought the ending made sense and really shocked me and i did not see that coming. I just loved learning more about the shadow hunters world and really just falling in love with the character. I highly rec. this series!
