What do you do when the world as you know it changes in an instant and you have to rely on two beings you never believed in? 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 trilogy will take you on an adventure as Cassidy, Dillon, Tasha and Jack look for a way to bring peace back to the Earth and stop the alien invasion. When bad things happen, can Cassidy rely on the two men - one alien and one ghost - who have both vowed to protect her? Or will one of them let her down? This series mixes aliens, ghosts and romance in a science fiction fantasy setting. If you love alien first contact books, this is a great series for you!
