It's been 99 years since Yellowstone park erupted, causing a mass extinction and plunging the world into an ice age. Survivors are living in a structure dubbed the Greenhouse. They believe they're the only survivors, until a message appears on the outside of the glass. Jack Paul lives in a land of ice and snow, and Ruby Hammond lives in a lush, tropical world where the sun always shines. Even though they're from such different world, their fates are so intertwined that they are destined to meet.

Bloomwood Preparatory is a prestigious boarding school in London. To get in, you must be incredibly talented or incredibly rich- preferably both. And if you do get in, you're elite. In every sense of the word. In such a world, where the millionaires and prodigies call the shots, Vivian Wentworth and Archer Woods are elected Head Girl and Head Boy of Bloomwood Prep in their final year. It's a great honour, and to uphold it, they must work together responsibly and harmoniously. There's just a slight problem. Vivian and Archer have a history they'd do anything to forget. And a chemistry they'd do anything to deny.
