The principals looked at each other. The grudge was gone.

And in the hallways of Cedar Ridge, Harbor Pointe, and North Valley, students no longer asked, "Which school are you from?" They asked, "What are you building—and who do you need to build it with?"

"Synergy," she said, "means the whole is greater than the sum of its parts. Starting today, Cedar Ridge’s award-winning robotics lab is open to Harbor Pointe students. Harbor Pointe’s theater department will produce a joint musical with North Valley’s choir. North Valley’s AP science teachers will host online review sessions for all EUHSD students."

Reluctantly, they agreed to a 90-day pilot. Chaos. Schedules clashed. A bus full of Harbor Pointe students arrived at Cedar Ridge with no teacher. A North Valley choir member refused to sing with "those Harbor sopranos."

AP review sessions went viral (within the district). North Valley's biology teacher, Mr. Okonkwo, livestreamed a dissection so clear that Harbor Pointe students sent him thank-you cards. Cedar Ridge's calculus whiz, a senior named Mira, started tutoring students from all three schools online. Her pass rate hit 94%.

"The math worked," she said. "We shared three buses instead of six. We combined our library databases. We even shared substitute teachers. Our total cost dropped 28%, but our student outcomes—college acceptances, test scores, arts participation—went up 15%."

A small win. The robotics teams combined forces for a regional competition. Two Cedar Ridge programmers, a Harbor Pointe designer, and a North Valley builder created a robot that could sort recyclables faster than any single school's design. They won first place.

Elena called a meeting. She didn't bring charts or budgets. She brought the robot, the stage model from Les Mis , and a stack of thank-you cards.
