My favorite crime novels always combine more than one genre. Like a detective mystery that's really psychological. Or a police captain who happens to be a gourmet. Honestly, most travel books don't even get going until a body or two is discovered.
In the case of Before I Burn by Gaute Heivoll, the mashup is suspense meets memoir. It sounds a little gimmicky, but I promise it's absolutely not. Instead we have a semi-autobiographical novel that's poetic, gripping and at times even profound.
