I started reading The Inheritance by Gabriel Bergmoser before realising it featured a character who’d appeared in The Hunted, released in 2020. It’s certainly not a sequel however, and previous knowledge isn’t required.
I didn’t like The Hunted as much as most because it dipped a little too much into the horror genre for my taste. I can cope with books about serial killers and psychopaths but Bergmoser has the impressive (if not entirely welcome to me!) talent of putting readers amidst action; which is often very violent and visceral.
