The story begins with Kendra and Seth going to visit their grandparents in Connecticut while their parents take a 17 day cruise without them. At first the siblings entertain themselves with an attic full of interesting books and toys, and a pond-like swimming pool surrounded by hummingbirds, brightly colored-butterflies and exotic dragonflies. But soon their attentions wander to the forbidden forest that surrounds their grandparent's house. When Kendra discovers a book entitled Journal of Secrets and follows the directions to "Drink the milk" a whole new hidden and amazing world is revealed to the siblings at Fablehaven. Inside the gated woods, ancient laws maintain relative order among greedy trolls, mischievous satyrs, plotting witches, spiteful imps, jealous fairies and beautiful naiads. However, when the rules get broken on Midsummer Eve, an arcane evil is unleashed, forcing Kendra and Seth to face the greatest challenge of their lives. To save their family, Fablehaven, and perhaps the world, Kendra and Seth must find the courage to do what they fear the most.
At the end of the school year, Kendra and her brother, Seth, find themselves racing back to Fablehaven—a refuge for mythical and magical creatures in Fablehaven: Rise of the Evening Star. The Society of the Evening Star, an ancient organization determined to overthrow magical preserves and use them for their own intents and purposes, is determined to infiltrate Fablehaven. Grandpa Sorenson, the caretaker of Fablehaven, invites three specialists to help protect the property: a potion master (Tanu), a magical relics collector (Coulter), and a mystical creature trapper (Vanessa). In addition, these three specialists have a more perilous assignment—find an artifact of great power hidden on the grounds. When the Evening Star pervades the gates of Fablehaven, it is assumed that someone inside the preserve is a mole and a traitor. If the artifact falls into the wrong hands, it could mean the downfall of other preserves and possibly the world. With good intent, Kendra and Seth become both a help and hindrance to their grandfather’s cry to protect Fablehaven.
Strange things are afoot at Fablehaven. The book takes off right where the second book ended, during the same summer of their second year at Fablehaven. Kendra and Seth helped save Fablehaven from the Society of the Evening Star, but new troubles present themselves almost immediately. Kendra and Seth discover that someone, or something, has released a plague that transforms beings of light into creatures of darkness. For the first time, some of the main characters visit another magical preserve, as another hidden artifact must be recovered from Lost Mesa in Arizona. New friends are introduced and new magical creatures of light and darkness are confronted. Can the plague be stopped? Can the artifact be found? Is the Sphinx a traitor? Will the plague eclipse all light at Fablehaven?
