We are finally at the close of yet another school year. For those of you graduating and moving on to new adventures, we will truly miss seeing you! We wish you well! For those of you that will be returning to CO, we look forward to seeing you next year on campus.

It is now time to return materials that you've borrowed over the last year. Seniors will need to return their Chromebooks in addition to any textbook materials, athletic gear or instruments they may have borrowed. Juniors, Sophomores and Freshmen will keep their Chromebooks, however will need to return all textbooks, athletic gear, and instruments. If you have AP textbooks and need them for studying, you may keep them until after the test. More information to come on a return date for AP textbooks.

Below you will find the schedule for returning materials. If you find that you are missing textbook materials or library materials you can pay by cash at the textbook windows (exact amount please).

What people have to say about Marie Lu and her books:

"I'm such a sucker for dystopians. I love the energy, the rush I get from them. When I got my copy of Legend I was thrilled. Now I know I had a good reason to be. This is one of the good ones. A dystopian well worth reading!"


"I LOVE THIS BOOK SO MUCH. You will love it too. It is beautiful and smart and Emika is a funny, flawed, *awesome* heroine. And Hideo, omg, SO MANY FEELINGS. The setting in this book are exploding with radness--the conversations, the technology, the intricacies of the world. I knew from both the LEGEND series and TYE that Marie Lu was a master worldbuilder, but this clinches it. "


"Warcross is absolutely one of my favorite books of the year. It's thrilling, it's engaging, and the twists in this novel are still driving me wild. I loved absolutely everything about this novel."







The Karensa Federation has conquered a dozen countries, leaving Mara as one of the last free nations in the world. Refugees flee to its borders to escape a fate worse than death—transformation into mutant war beasts known as Ghosts, creatures the Federation then sends to attack Mara.


The legendary Strikers, Mara's elite fighting force, are trained to stop them. But as the number of Ghosts grows and Karensa closes in, defeat seems inevitable.


Still, one Striker refuses to give up hope.


Robbed of her voice and home, Talin Kanami knows firsthand the brutality of the Federation. Their cruelty forced her and her mother to seek asylum in a country that considers their people repugnant. She finds comfort only with a handful of fellow Strikers who have pledged their lives to one another and who are determined to push Karensa back at all costs. When a mysterious prisoner is brought from the front, Talin senses there’s more to him than meets the eye. Is he a spy from the Federation? Or could he be the weapon that will save them all?


For the millions who log in every day, Warcross isn’t just a game—it’s a way of life. The obsession started ten years ago and its fan base now spans the globe, some eager to escape from reality and others hoping to make a profit. Struggling to make ends meet, teenage hacker Emika Chen works as a bounty hunter, tracking down players who bet on the game illegally. But the bounty hunting world is a competitive one, and survival has not been easy. Needing to make some quick cash, Emika takes a risk and hacks into the opening game of the international Warcross Championships—only to accidentally glitch herself into the action and become an overnight sensation.


Convinced she’s going to be arrested, Emika is shocked when instead she gets a call from the game’s creator, the elusive young billionaire Hideo Tanaka, with an irresistible offer. He needs a spy on the inside of this year’s tournament in order to uncover a security problem . . . and he wants Emika for the job. With no time to lose, Emika’s whisked off to Tokyo and thrust into a world of fame and fortune that she’s only dreamed of. But soon her investigation uncovers a sinister plot, with major consequences for the entire Warcross empire.


What was once the western United States is now home to the Republic, a nation perpetually at war with its neighbors. Born into an elite family in one of the Republic's wealthiest districts, fifteen-year-old June is a prodigy being groomed for success in the Republic's highest military circles. Born into the slums, fifteen-year-old Day is the country's most wanted criminal. But his motives may not be as malicious as they seem.


From very different worlds, June and Day have no reason to cross paths—until the day June's brother, Metias, is murdered and Day becomes the prime suspect. Caught in the ultimate game of cat and mouse, Day is in a race for his family's survival, while June seeks to avenge Metias's death. But in a shocking turn of events, the two uncover the truth of what has really brought them together, and the sinister lengths their country will go to keep its secrets.
