In the heart of Gristle Grove, Halloween is more than tricks and treats—it’s a gateway to secrets hidden just beneath the cobblestones. Calvin, an intrepid boy with a homemade vampire-hunter’s hat, and Pudge, his ever-loyal beagle in a wizard’s cape, thought they’d seen it all. But when a mischievous ghost named Gus and a mysterious spectral guide named Elowen emerge from the shadows, they discover that under the Halloween moon lurks an ancient, unseen doom—and only friendship, courage, and a little moonlight magic can save their town.

Join Calvin, Pudge, Gus, and Elowen as they journey through haunted libraries, hidden wells, and forgotten catacombs, solving riddles, warding off spectral horrors, and forging a new Halloween tradition: the Lantern of Light Vigil. This isn’t just another spooky story—it’s a testament to the power of loyalty, the thrill of mystery, and the light we carry when we stand together.

One boy. One beagle. One ghostly guide.
Under the eerie glow of the Halloween moon, Gristle Grove’s strangest mysteries come to life. When jack-o’-lanterns scream, stones stir beneath the earth, and shadows slither through the library stacks, only Calvin—with his wooden slingshot and fearless heart—and Pudge—with his magical wizard’s hat—stand between their town and an ancient, all-consuming doom.

But they’re not alone. Gus, a repentant ghost burdened by past failures, and Elowen, the silver-cloaked Watcher, join forces with Calvin and Pudge to unravel cryptic runes, rescue lost souls, and reignite the Lantern of Light Vigil—a new Halloween tradition. From haunted attics and hidden wells to midnight masquerades and moonlit rituals, Calvin and Pudge and the Unseen Doom Under a Halloween Moon is a heart-pounding, laugh-out-loud adventure that proves the greatest magic of all is friendship.

Will their courage be enough to banish the shadows once and for all? Light your own lantern and discover the answer—if you dare.
