The Line Between – Tosca Lee, 2019. 4.5/5

An apocalyptic pandemic. A religious doomsday cult. A naïve heroine with the key to earth’s salvation. Lee hits all the right buttons in this breakneck page-turner.

Wynter Roth is seven years old when her mom, fleeing her abusive husband, brings Wynter and her sister Jackie to the isolated New Earth compound. The cult is led by the handsome, charismatic, and shady ex-entrepreneur, Magnus Theisen. Despite being the New Adam to his flock and preaching of end times, he maintains his worldly business influences and illicit desires.

Initially, Wynter and her family find safety and acceptance in the community—at the expense of their freedom of thought and individuality. Things deteriorate when Magnus takes Jackie as his new wife and plans to add Wynter as a second. Wynter is disgusted with Magnus’ hypocrisy and loses faith in his divine vision. At twenty-two, Wynter is cast out and taken in by an old friend of her mom’s.

The world is hard to navigate. Information is overwhelming, and Magnus’s dire prophecies and condemnation echo in Wynter’s head.

But it’s more than that. People are going crazy. Forgetting things. Killing themselves and others in graphic, violent ways. The CDC calls it early onset dementia—and it’s contagious and spreading like wildfire. The U.S. descends into chaos. Gas and supplies run out. Power grids go down.

Wynter is the only hope. Jackie escapes New Earth, bringing Wynter a case of medical samples acquired by Magnus that may hold the key for a vaccine—but not a cure. Wynter must race the specimens across the ravaged Midwest and deliver them to a researcher in Colorado.

The Line Between keeps tensions high, alternating between Wynter’s gripping memories of emotional abuse in the cult, and the mounting present-day horrors as society disintegrates around her. Everything is distressingly, immediately believable: from the nature of the disease laying waste to humanity, to the country’s nosedive into anarchy.

The thriller aspect alone makes this a standout novel, but Lee elevates the story further with layered, convincing characters, both good and bad. Wynter is beautifully drawn: she wrestles with self-doubt and her ignorance of the modern world but nurses a spark of independence and determination that even Magnus can’t destroy. On her quest, Wynter experiences tragedy and cruelty and selfishness, but also kindness, generosity, and…potential romance. The ending resolves major plot threads and sets us up nicely for a sequel. Which I want immediately, please.
