Two families, one secret that will tear them apart. Evelyn loves Bryce, but Bryce is not who he says he is. Unbeknownst to Evelyn, neither is she. In a place where many worlds exist, Keepers guard the gates between them, and Watchers command the Keepers. However, an archaic war between Watchers and Keepers ensues, which threatens to destroy Evelyn and Bryce's happiness if Evelyn's best friend, Sylvia, does not come in between them first.
