"Some Math Club nerds have got a real live alien! They're hiding it in a basement rec room!"

Now available in full length for the first time comes the first book in a series about young humans confronting an age-old theme — that of strangers from beyond — giving it new shape, guided by the deft hand of one of science fiction’s modern masters.

High School junior Mark Bamford doesn’t believe the silly rumor. For one thing, here in the town of Twenty-Nine Palms? California homes don’t have basements! Besides....

A stranded alien? Seriously? Can we say c-l-i-c-h-é? Movie rip-off? Can’t the math geeks think up a better hoax?

But then... Why are black vans from the super-secret Cirrocco Corp cruising all over town, searching for something?

Mark and his pal Alexandra decide to do some investigating of their own. Only, where can they turn for help? The skateboarding “X” crowd? The varsity climbing team? It’s not like their social circle is an elite spy force!

Perhaps though... with home grown ingenuity, a little sleight of hand — okay, call it double-dealing, whatever.

The truth isn’t just ‘out there.’ It may be right next door.

NEW RELEASE! Castaways of New Mojave, Book Two in the High Horizon series.

more about the HIGH HORIZON series of YA science fiction

Colony High is the first book in High Horizon, a YA science fiction series based on the award winning novel Sky Horizon, from acclaimed New York Times Best-Selling novelist David Brin.

When a group of teens rescue a stranded alien, humanity is rewarded with a "gift": their entire high school, along with a quarter-mile radius of town surrounding the school, is transported to a new planet, millions of light years from Earth. 1200 'colonists,' mostly teens, must learn to survive in a strange and hostile environment. The High Horizon series follows their plight as they struggle to survive, and uncover a trail of bizarre clues to solve the mystery of why they are there — and if they will ever see home again.

Was humanity really given a gift? Yes... of a sort. Only now, led by our hero (who must become a new Moses), these pampered American teenagers have to grow up very fast. They will overcome violent challenges in order to save themselves... and eventually their homeworld, Earth.

This is a coming of age story, as teens transform into leaders, villains, and heroes. Some rise to the challenge, while others, unable to accept their new reality, descend into despair. Each must choose a path to follow as they come to grips with their harsh surroundings.

NOW AVAILABLE! Castaways of New Mojave, Book Two in the High Horizon series.
