She'd reconciled her life without him. His return would be Bittersweet. Welcome to Mother Cora’s, where the offspring of the Kaveesh learn to coexist with humans. One hundred and twenty years ago, the Kaveesh came to Earth to save the dying planet from a disease that gorged itself on anything in its wake. Buildings crumbled to dust. Soil and plant life were consumed. Two-thirds of the Earth’s population perished. The only thing the Kaveesh asked in return was to help save their dying race. Breeding programs began and the half-breeds were born. Lirabel is a half-breed and an overachiever. Despite a few setbacks, she’s scheduled to graduate early from Mother Cora’s and become the Half-breed Ambassador to the Humans. Enter Jonas. They were best friends until he broke her heart and disappeared five years ago. Now, he’s back, but Lirabel couldn’t care less. There are more important things to worry about… Like finishing her last year of school and becoming ambassador. Or the half-bred students losing control of their Kaveesh strengths who are being sent into quarantine. Or how the breeding programs are still up and running. And somehow, Jonas’ bittersweet return is connected to it all.
