Better Off Dead

Promised a cure for her immortality, Petra joins a quirky crew without question. She should have asked questions.
15 years ago she lost half her body in a totally avoidable accident in her father's non-IKEA-standard lab. He used the tissue-fusing serum he created to save her, but it left her with major confidence issues, pesky immortality, and a body that's 40% raw meat. Some people have the worst luck.
With half a face and the body of a child zombie, she eventually runs out of options. When a profiteering scientist turns up with the serum she thought her father destroyed all those years ago, she's dragged into the middle of his villainous scheme by the ragtag team assembled to stop him. Mostly. Petra's just in it for the cure they're making.
Get the serum, make the cure, die. It's a simple plan. But things go south on their northwestern island when she witnesses a murder.
