The Darkest Hour story includes romance, suspense, family, friends and is full of emotions. Ethan and Rachel go through hell as individuals and as a couple; with the love and support of their family (Ethan's) they are determined to get through their tortured emotions and past to move forward and be truly happy again. 
 I cannot speak for anyone other than myself but, their story jerked at my heart strings. I enjoyed this story and look forward to reading the rest of the KGI series.
