What if you woke up one day with cool new assassin skills?

That’s what’s about to happen to 16-year-old Lorna Walker, the most unlikely heroine you’re likely to meet.

When a mysterious transplant donor turns up dead from a bullet wound, social outcast Lorna gets the new heart she needs to return to live a normal life again.

Little does she realise, she’s just swapped one life or death struggle for another.

As if the strange memories and embarrassing new behaviours aren’t enough, she’s also inherited a set of killer new skills landing her deep in trouble.

Then there’s the mystery object her donor hid before he died. It’s put her top of a secret kill list. And the only way to survive now, is to run.
