Children's book about a girl with amnesia & conspiracy around it?

Hi. I'm searching for a series of books I read when I was about 12. I don't remember the title or author at all.

It was about a girl who woke up with amnesia after her house burnt down. She began to discover some sort of conspiracy surrounding the fire and her amnesia.

I don't remember the main characters name, but there was another girl named Mango who befriended her as part of the conspiracy.



I know that all this is exceedingly vague, but if anyone has read anything similar to this, I would love to know!Children's book about a girl with amnesia %26amp; conspiracy around it?
Maybe the Chasing Yesterday series by Robin Wasserman. The first title is Awakenings.
