The Secret of the Sapphire Sentinel

By Jendia Gammon, writing as J. Dianne Dotson

The Secret of the Sapphire Sentinel by Jendia Gammon, writing as J. Dianne Dotson, is the sequel to the Nebula and BSFA Award finalist The Inn at the Amethyst Lantern. This is the second book of a trilogy.

Summer is over in Glimmerbight, and the shadows of new threats emerge in this Night Living future. Gen Lightworth finds herself at the forefront of a new crisis. 

Meanwhile, school is starting. Along with the requisite drama, some of the teachers may not be who they seem. Gen must disobey her parents and step up to be a leader again, while wrestling with her feelings and trust for someone who comes back into her life at a pivotal moment. While at school, Gen uncovers a secret: there were multiple old light stations from ancient times.

One of them, the hidden Sapphire Sentinel, could provide the power necessary to reboot the Source and protect Glimmerbight. But not if the villains get there first. The Sapphire Sentinel itself carries its own unique and powerful secrets that could change the future.
