Received an advance reader copy in exchange for a fair review. Thanks to NetGalley and Little, Brown Books for Young Readers for the opportunity to read and review Defy the Stars by Claudia Gray! Noemi is a soldier for Genesis and she’s very loyal to her planet and her friend, Esther. Abel is a machine made by an Earth scientist to be the culmination of all other machines that have been created. The scientist, Mansfield, wants Abel to be as human-like as possible, including feeling emotions and having conscious thought. Esther is injured and Noemi finds the functioning but deserted ship, the Daedalus, not knowing that Abel is on board. Noemi wants to help Esther by getting to the ship’s sickbay. Abel does everything in his power to save Esther and he and Noemi become reluctant comrades while Abel treats Noemi as a commander. They are going together to destroy the gate between Earth and Genesis. On their trip they make discoveries about each other, such as integrity, loyalty and other values and skills. They also note each other’s intelligence. The mystery of Abel’s creation and purpose makes both of them more and more curious. They meet and befriend others while on their quest and the action and suspense continues to build. This story turned out better than I thought it would, since science fiction isn’t my favorite genre. Claudia Gray built a complex, futuristic world full of diverse and dynamic characters, 5 stars !
