Looking for a futuristic book with some kids and this weird lady who loves robots

Question

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?

Answer 1

I found it.
