The Secret of the Sapphire Sentinel

By J Dianne Dotson

In the twilight world of Glimmerbight, fourteen-year-old Gen Lightworth dreams of restoring the Inn at the Amethyst Lantern. But an ancient evil's lingering scars awaken new threats from unexpected corners.

Summoned by the mysterious Gallant Twilight Society-a network of heroic animals-Gen journeys beneath the waves into hidden lairs pulsing with bioluminescent secrets. With her loyal team, the Fireflies, she confronts lost legacies, mutated monsters, and shadowy figures from the past.

When a vibrant yet unsettling new apothecary arrives, secrets multiply and trust frays. And as danger closes in, Gen learns the true weight of leadership and the strength of friendship.

Filled with wonder, bravery, and the luminous bonds of community, The Secret of the Sapphire Sentinel continues the saga begun with the Nebula-nominated novel, The Inn at the Amethyst Lantern. Join this unforgettable adventure where light battles darkness and friends navigate mysteries beneath the stars.
