Siri, who am I? (Hardback original)

When Mia wakes up in a Long Beach hospital with a head wound, she knows everything there is to know about the Kardashian-Jenner family but almost nothing about herself.

The only items in her possession are her torn party dress - which immediately begs the question, what kind of girl parties on a Tuesday night? - a tube of Chanel lipstick, and an iPhone with a shattered screen.

She might not remember where she lives but she can use her Instagram account to work backward to piece together the basic facts of her identity.

Easy enough, right? Instagram tells her that she lives in a Millennial-pink duplex that would make Kylie Jenner jealous.

But when she arrives, she discovers a cute housesitter named Max who tells her the house actually belongs to JP, a French billionaire - and he has no idea how she's connected to him.

After some sleuthing, she discovers she's the owner of a high-end matchmaking service.
