I just met my long-lost sister — and now she wants me to do something bad.

It started with a DNA test and a match on a genealogy site. One click, and suddenly my world flipped. I have a sister I never knew about.

Callie Madden-Bramston — gorgeous, wealthy, married to a man who looks like he stepped off a yacht. Her life is all designer handbags and luxury holidays.

Mine? Not so much. Maxed-out credit cards, secondhand clothes, a history of bad choices and eviction notices.

I didn’t start off looking for anything from her. I just wanted to get to know her. But when we finally meet in a coffee shop, Callie makes it clear: she’s not here to play sisters.

So why do I say yes when she asks me to do something very dangerous?
