Do we really need another teen heroine super soldier battling endless worlds of potential monsters for a corrupt government bureau? Not to mention the high body count and the perfect boyfriend. With cameos by a pastel highlighted unicorn and a wise reptile man you know is meant to be played by Danny Glover.

Ryn Whittaker is working at her job as a Citadel, an enhanced soldier who guards the gateway to other Earths, when a young man, Ezra, comes through. She feels they have an immediate attraction and promises to see him again, but his intelligence and curiosity lead him to discover some things about the ARC and the Rift that no one is supposed to know. It's up to Ryn and Ezra to figure out a plan to stop ARC from sending the Citadels on a suicide mission and destroying all the other Earths. ( )
