Book One: Yesterday’s Gone

It’s the summer of 1986 in a small town in Washington State. Twelve-year-old Adelaide Winter spends her days biking around, bantering with friends, getting lost in music, and wondering what the new school year has in store for her.
Everything changes when Darius Belcouer moves to Olympic Vista. He has a nose for adventure and loves a good mystery. And he’s certain the research and development facility in town, referred to as The Link, is hiding something big. What starts as a simple outing to a local haunted house reveals something so much more than he or any of his new friends could have expected.

Book Two: Songs from the Woods

The haunted house was only the beginning.
Twelve-year-old Darius Belcouer knows the quiet town of Olympic Vista is anything but normal. After uncovering the dangerous truth about a house thought to be abandoned, Darius and his best friend, Adelaide Winter, are only left with more questions: Who were the secret agents they crossed paths with, and how do they connect to The Link?
Darius is desperate for answers and another mystery—and the strange little town is ready to deliver.
While school is in full swing, news of a series of unusual and brutal animal attacks sends a shiver through the community. Darius and Adelaide know immediately this isn’t the work of an ordinary predator. The trail of evidence leads them into the forest behind Adelaide’s house, but as the local wildlife turns vicious, the pair quickly realize that the horror lurking in the shadows might be more than they’re equipped to face. The woods are alive with a terrifying new threat, and it may be tied directly to the answers they’ve been seeking.
Some secrets won’t just stay buried. Some of them bite.

Book Three: Costumes & Copiers

In a town like Olympic Vista, weird doesn’t take a holiday.
The copy centre where Adelaide’s mom works shuts down suddenly overnight and Belinda is unemployed. Again. No one seems to have any answers. Is something supernatural at play? Or can they blame Belinda’s infamously bad luck?
And then, with Halloween right around the corner, Adelaide and her friends’ attention turns to costumes! Dizzy Izzy’s Costume Emporium, a new pop-up shop promising the perfect disguises, is more than happy to help. Only when the evening of the big Halloween party arrives does the true horror begin.
Now, Adelaide and her friends must solve yet another mystery before the most magical night of the year becomes a permanent nightmare of tricks, treats, and a terrifying transformation.
Get ready for the wildest, scariest Halloween in Olympic Vista history!

Book Four: Farmhouse Fiasco

They thought Halloween was over. They were dead wrong.
It’s late Fall 1986 in Olympic Vista, and twelve-year-old Adelaide Winter is desperate for a distraction from life at home. And in this strange Pacific Northwest town, a little weirdness is never far away.
The new mystery arrives as a spooky rumor: a floating jack-o’-lantern hovering over an old farm. Adelaide quickly rallies her friends for a late-night mission, only to have their plans unravel before they even step onto the property.
Caught in a situation unlike anything they’ve faced, with danger lurking in every shadow, the preteen sleuths must pull together.
In Olympic Vista, the tricks don’t stop just because the calendar says November.

Book Five: Birds of a Feather

When Clayton, the older brother of their classmate Colin, goes missing, Darius, Adelaide, and the rest of the group are on the case. Their best lead takes them through a mysterious archway in the woods—and straight into a parallel world where disaster has struck.
When an old friend resurfaces, Adelaide learns she might be hiding her own secret.
It’s a race against the clock as the friends search for Clayton in the strange ghost town. Can they get home in time to stop their own world from suffering the same fate?

Book Six: Secrets Past

Darius had known there was something strange about Olympic Vista the moment he arrived last summer. Since then, he, Adelaide, and their friends have survived secret agents, a haunted house, vicious animal attacks, and a night of cursed costumes. And Darius’ obsession with the weird happenings in Olympic Vista has only grown since he discovered his father may know more than he’s been letting on.
But Adelaide is ready to put all the sleuthing behind her. She finally has a life that feels normal: homework, baking, friends, and—best of all—a miraculously calm house. And the last thing she wants is for her friends to discover the big secret she’s been hiding from them.

Book Seven: Home to Roost

Life is finally feeling normal for Adelaide Winter. Her mother has a steady job, there is food in the cupboards, and Adelaide has lots of time to spend with her friends and her dog, Pepper. If it weren’t for her mother’s friend, Steffi, life would be perfectly normal for Adelaide.
But in Olympic Vista, “normal” is always an illusion. And the cracks are showing.
MALTA vans have been spotted throughout the town, Darius’ father has a strange visitor, and there’s something weird in the woods. Darius knows he’s close to the biggest breakthrough yet, but the strangest thing of all is Adelaide’s reluctance to investigate any of it.
