A pop star in peril. A coven in the woods. And a code magic can never hide.
Step into mysteries that demand courage, discernment, and the will to seek the truth. Conceived and co-written by the daughter of Robert Arthur - the creator of the Three Investigators universe - this restoration of the classic series takes its iconic characters into a new age, with gripping contemporary adventures for young readers who crave meaning, want to share in the growth of characters they admire, and seek a world they can return to again and again.
In the eleventh book of a 26-book story arc, The Three Investigators' anticipated vacation takes an unexpected turn when Pete and his friend Branko find a lost dog during an afternoon run near the Petrovic family's property in Jackson. The dog belongs to Odetta Dharmapuki, a famous pop star who lives nearby, and the boys - along with Brando, Mallory, and Pete's secret crush Califia Garcia-WIlliams - resolve to return her to her owner at the end of their raft trip.
But when they meet Odetta, it's clear that there's more to this situation than a missing dog. Odetta's new boyfriend, Zachary Hughes, a developer at Apple, has recently been arrested for an altercation with a paparazzo. This incident is just the beginning of a deeper, more unsettling mystery. Someone with a high level of technical expertise is harassing Zachary - and by extension, Odetta - through sophisticated means, tracking their movements and compromising their privacy.
The Three Investigators quickly realize that they've stepped into something far more complex than a simple case of celebrity stalking. The clues are scattered, but some seem to point back to a mysterious group, a Wiccan coven known as Circle of the Mirror. What is Zachary hiding from his past at MIT? How does the failed technology company Memory Bank fit into the puzzle? What role do Odetta's kaleidoscopic light shows play in the harassment? And why are a cloaked woman and a homeless man living in a cave seemingly connected to it all?
Things escalate when Odetta's estate is firebombed, and the team is thrust into a dangerous rescue mission. Tensions rise as Mallory and Califia - disguised as members of the coven - join a secret ritual during the full moon, while Jupiter and Branko delve into the dark secrets lurking beneath in a basement.
Join Jupiter, Pete, Bob, Branko, Mallory, and Califia as they enter a sinister tangle of jealousy, thwarted desire, hidden secrets, and dangerous tech in this heart-pounding new chapter of The Three Investigators series. With lives at risk, can they expose the truth before it's too late?
