Rise of the Evening Star

Kendra and Seth return to their grandparents’ hidden preserve and quickly uncover a dangerous conspiracy: a secret organization called the Society of the Evening Star is working to free dark forces and seize powerful magical artifacts. Forced into daring missions and uneasy alliances with mythical creatures, the siblings must outwit traitors, face escalating threats, and grow into their own strengths—Seth’s impulsiveness and Kendra’s courage are pushed to the limit as they race to prevent a catastrophe that could endanger both the magical and human worlds.
