Fenrir. Volume I. Border Breaker

You’re always five minutes from death. Every next breath resets that timer. Though I’d argue about how many minutes there are, if I have to surface from the bottom of a river in mid-October.
Alright. My name is Andrey Davydov. And now I’m the main character. If I don’t die, damn it, before I reach that coveted air.
Five minutes, you say?
A sequel to the “Phoenix” series.
