Kids say the book features an engaging plot and well-developed characters in a vibrant virtual reality setting, but contains some romance and kissing scenes that may not be suitable for all younger readers. While many found it exciting and loved the twists and action, critiques include the need for clearer explanations in parts of the story and some felt the romance was forced or predictable.

What's the Story?

As WARCROSS opens, bounty hunter Emika Chen finds herself on the brink of eviction from her apartment and complete financial disaster. But when she impulsively hacks the opening ceremonies for the international Warcross Championship, she unintentionally reveals herself in front of a global online audience. She becomes a pop sensation overnight and is whisked off to Tokyo to be a wild card contestant in the tournament. On top of that, Warcross inventor Hideo Tanaka takes a personal interest in her, one that will threaten the entire championship and put Em directly in the path of danger.

Is It Any Good?

Our review:
Parents say ( 3 ):
Kids say ( 21 ):

Cyberpunk fell out of favor for a while, but this futuristic thriller jump-starts the genre and sends it careering in a promising new direction. Marie Lu has proven her skills with dystopian fiction and pseudo-medieval fantasy, and now she displays a steady hand with virtual reality in Warcross. Lu has created a winning protagonist in Em, and her perceptive and plucky narrative voice keeps the story moving, even when the action turns a little talky. Suspense and romance take a while to rev up, but eventually Warcross is firing on all cylinders. Readers should be aware that the book ends with a cliffhanger, but it's a doozy, one almost guaranteed to compel fans to return for the second installment.
