I love YA books, and Marie Lu is one of my favorite YA authors. If you think you don’t like YA books, try hers. I think Lu’s appeal to all ages because of her crisp writing and her fascinating characters. Winter Young is a superstar! A billionaire hires him to perform at Penelope’s birthday and Sydney, an undercover spy, is hired to be Winter’s bodyguard. Sydney’s real job is to infiltrate the billionaire's criminal organization. I really loved the insight into Winter's life, both professional and personal. His backstory was really well thought out and made him feel realistic. The story was well-paced and if you love action the end was action-packed! I’m not a fan of romance, but there wasn’t an annoying amount so I didn't mind. But if you love romance there is probably enough for you.
I am already anticipating the next book about Winter and Sydney. 4.5 stars rounded up to 5.
