I love how Greek mythology is tied into this re-telling, it's completely different from the original. Rosamund Hodge draws you in immediately during the prologue. It leaves you wanting to know more about this mysterious world she created. Sometimes it's difficult to get into a third person past tense, but it was not an issue with this book. 
 The main character is a bad-ass assassin/warrior that isn't completely human. She's what they call a "bloodbound". These bloodbound have heightened human abilities so they kick ass during fighting. Rachelle Brinon (protagonist) is not your typical damsel in distress lead, she's strong and knows how to get stuff done. 
 The story revolves around finding a way to stop the endless night. Even though the blurb on the cover makes it seem like this novel is romance driven it is not. There is romance, but it's gradual and happens later on. You'll see much more searching and fighting than love here. 
 Rachelle has always wanted to act rather than sit around. Will the decision she dreaded to make pay off? Will she be able to save the world? Most of all will she take the path of needles or the path of pins. 
 If you're a fan of retellings or of Cruel Beauty then you'll most likely enjoy this novel. Warning there is a love triangle. 
 Overall I liked it but I didn't feel as emotionally connected to the characters as I wanted to be. It wasn't the type of book that you couldn't put down for me. The romance was also a little odd? It felt a little rushed even though it took forever for it to start. If that makes any sense.
