Another great story by Marie Lu! No surprises there. Marie's latest world leads us to the lives of spies. Sydney is part of an elite cover ops group. When there is something that needs to be done and the government can't do it, they are called in. And in her latest mission she is required to go undercover as a bodyguard and work with an international pop start, Winter Young. Winter may have this famous life, but it's not all that it is cracked up to be. At moments, he wonders if there is something more he can be doing. And when he is recruited by Panacea, he is at first reluctant to be some sort of spy, but is soon convinced that he can help. Especially when they have information on the death of his brother. Sydney and Winter are an unlikely pairing. But both surprise the other in so many ways. Their chemistry is full of banter and snark that you can't help but love. Their mission is to infiltrate a crime organization's boss and get the proof to finally put him away. There will be plenty of twists and turns, and revelations that will keep you one your toes. As always in Marie's books, there is lots of action and romance, and a great story line. It took me a bit to get into the story but once I hit a point, I was hooked and couldn't put it down! Hoping to see more in this world. And definitely more of Winter and Sydney.
