I read this book around 5 years ago. It's got a futuristic setting with the usual - diseases, gene editing, humanoid robots . . .
This is what I remember from it:
The book cover has some kids on bicycles. I don't remember the number of kids, but they're looking at some bubble (apparently the bubble is there to keep diseases out?)
The main character is the granddaughter of some rich person (or scientist)
There's this weird perfect girl that shows up; She has this natural charisma that makes the main character and her friends what to listen to her
There's this weird mom of one of the friends of the main character that talks about robots and the cloning technology that is possible . . . she focuses upon the new girl with this weird intensity and says something like "You will love this!"
I think the perfect girl's name started with either an I or an A?
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?
In a stunningly imaginative story, critically acclaimed author Megan Frazer Blakemore takes readers on a journey with five friends--new and old--that will have everyone talking about not just what makes people human, but what makes them true friends.
