Brave the Plex. Unleash the stone. Embrace your destiny. Freshly freed from an earth-dwelling monster, Juniper Conway is stuck with a promise she never intended to make. But if rescuing Plex City from a deadly nano drug is what she vowed, it's what she'll do. Miles of wasteland stretch between Juniper and the domed city. In the Texas Outer Grid, following a tribe of whalers seems to be her best bet at surviving the chaotic storms. But when the nomadic tribes prove just as dangerous as the Grid itself, Juniper realizes her streak of bad luck is far from over. Only her shipping crew friends can help her through the waste and into the Plex. When the crier stone guiding her mission only shows her fragmented steps, Juniper will need more than the stone around her neck and a halfhearted promise to make it out alive.
