The Firefly Code

Mori and her friends live a normal life on Firefly Lane in their utopian community, Old Harmonie. In a world this safe and perfect, they've never had to question anything...never had to wonder about how their lives came to be. Until a new girl named Ilana moves in. She's so perfect that Mori and her friends are curious.... Where exactly did Ilana come from, and why does she act so strange sometimes? When Ilana's secret is revealed, the kids on Firefly Lane must decide: Is it finally time to start questioning the only world they've ever known?

Mori and her friends Julia, Benji, and Theo have never seen the world beyond the walls of their utopian community, Old Harmonie. That changes when their new friend Ilana is threatened by the rules that are supposed to keep them all safe. Together, they escape, hoping to find help in Boston with Dr. Agatha Varden, one of Old Harmonie's pioneering founders. But as they encounter kids from the outside and face challenges they never expected, Mori and her friends begin to understand the complicated reality of their supposedly perfect world.
