A deadly virus forced civilization into groups based on blood type in this near-future dystopian, perfect for readers of The Handmaid’s Tale and Emily St. John Mandel’s Station Eleven.

O Zone, 2042. The Ekonovirus made blood groups lethal to one another. Survivors are segregated by blood type into districts devoid of modern technology and comforts, and crossing borders is forbidden in an effort to halt the spread of the disease.

Thirty-five-year-old Maggie is an Invulnerable—immune to the virus due to her rare AB blood—allowing her to traverse regional borders. Not that she ever wants to leave Lara, her younger sister and the reason she chose to live in O Zone. But when Maggie is asked to help an at-risk pregnant woman in District A, she agrees, despite wanting to keep her invulnerable status a secret. Sam—an experienced courier, a fellow Invulnerable, and someone Maggie never thought she would see again—leads the way. Before long, Maggie becomes a midwife mentor to a group of District A women and must decide if she can open her heart to Sam for a second time.

But when Lara becomes pregnant and develops a life-threatening condition, Maggie knows that the only hope for Lara and her baby lies with the hoarded medication from the highly militarized B Territory. Sam and Lara insist it’s a death wish. B Territory is notorious for its rumored experimentation on Invulnerables in search of a cure.

But Maggie has no choice. And what she finds in B Territory threatens everything she’s come to know about the new world.
