This novel was so intriguing. I couldn't put it down. This was the first novel of Caragh O'Brian's that I have read and I was absolutely floored. She knew exactly when to reveal secrets and when for key events to be placed in the plot line for the story to flow perfectly. It was fast-paced but not confusing. The themes of loyalty and trust were spun in efficiently and effortlessly.

For me endings always seem to be my least favorite part of novels and where I find my largest critiques. This one seemed very abrupt. Almost so much that I kept flipping through the last pages wondering where the ending was, the conclusion. I also found some events throughout the novel to be predictable. I love to be surprised in a novel, having many twist and turns. The big events however where not predictable and it still had many secrets and surprises.
