From here the story moves both forward and backward in time as Jake both seeks out the killer and recounts how she came to the island and why she's so intent on isolating herself there. Her past, disorienting in large stretches because of its Betrayal-like structure, eventually reveals such horror and anguish that the beast could rightfully be viewed as either the epitome of her victimhood or a long-overdue judgment of her sins. This is a harrowing read; the monster and animal slaughter are perhaps the 10th-most depraved thing on display. It touches on torture, sexual slavery, and the crimes against Australia’s Aboriginal population, but Wyld isn’t simply going down a checklist of horrors—everything is done to illuminate the erosion of Jake’s soul and conscience. It's a magnificent book about grisly things, an experience not easily forgotten.
