Join Regina Shen as the exiting, great, daring, and dangerous adventure continues in book three of the Regina Shen Series, Defiance. Regina is still on the run and continues to elude capture from the patrol-women who want her for her DNA in hopes to reverse a worldwide fertility catastrophe, as they think Regina’s genes are the key to saving the world. Having previously taken and tested Regina’s sister, Colleen, but found her DNA lacking, the patrol-women now want Regina more than ever. But Regina perseveres and comes up with a plan to barter for her own freedom and that of Colleen as well. But this plan leads Regina on a dangerous and thrilling journey not only across the Alaskan wilderness, but a personal journey to also discover herself, as Mo-Mere previously instructed and suggested. I would recommend this novel to teens that enjoy science fiction and dystopian fiction.
