I enjoyed this take on snow white, it's darker, includes more magic, and gives the prince his own tragic storyline. 
The heart mending ability was intriguing, and it was emotional seeing Snow try so hard to help, but be shunned and despised by everyone for her magic. 
I liked the twists with memories, and additional magical creatures. It gave refreshing depth on top of the fairytale, and made the characters more complex. It had some drama, action, adventure and conflict, and some brutal revelations and twists. 
This was a nice and quick read, with minimal romance, lots of intrigue and danger, and that fairytale charm.
