4.5 stars! Letting Go is a deeply felt, elegantly written story of sexual exploration and desire. Joss is trying to move on with her life after the sudden death if her beloved husband. Little does she know that his best friend Dash has always been in love with her but never acted on his feelings out of loyalty to his best friend and Joss' husband. Sparks literally fly when she walks into Dash's D/s club one night, and he realizes she is looking to be in a submissive relationship. He is shocked but thrilled at the possibility of a relationship with her. 
 Maya Banks can write hot and steamy sex scenes like nobody's business! Wowser! What was beautiful about the story is that Dash and Joss had a deep connection before they have sex and there is a slow and gradual build-up to their scenes together. I loved when Joss really "saw" Dash for the first time as a man and a sexual partner, instead of the best friend of her husband. It was breathtaking. 
 The sex scenes are totally hot and the anal play scenes are absolutely among the hottest I have ever read! There is a fabulous Epilogue and no cliffhanger, but there will definitely be more books in this series about Joss and Dash's friends. Can't wait for more from Maya Banks!
