What do you do when your choice seems to be impossible, but you're forced to make it anyway?" Cassidy is just a normal, average, everyday high school student living in the year 2123 - but things are very different now. And when things - strange things - start happening around her, she finds herself caught in the middle of two worlds, being protected by two beings. When both her best friend and her parents come up missing, Cassidy is forced to rely on Jack (a ghost who has apparently been hanging around her for quite a long time) and Dillon, a seemingly normal high school student who turns out to be something totally different. This series mixes aliens, ghosts and romance in a science fiction fantasy setting.
