WHETHER VIOLENT OR NATURAL

The narrator of British author Calder’s eerie dystopian novel is a young woman living on an isolated island within sight of a mainland ravaged by infection.

The novel’s greatest draw is the woman’s enthralling voice, archaically formal and casually poetic. Whether her story makes sense or should be trusted is another matter. She avoids explaining why she’s ended up on the island, secure in a well-stocked bunker under a disintegrating ancient castle. Her sole companion is handsome, mysterious Crevan, who joined her some time ago and calls her Kit though it’s not her name. Although she sometimes, creepily, calls him daddy, he is clearly not her father. Nor are they lovers, although the sexual tension can grow intense. She prefers not to dwell on risk and considers Crevan paranoid. He repeatedly promises he will never hurt and always protect her, but she doesn’t trust stories about his previous life and how he was forced to kill in self-defense. Still, she’s fascinated by his explanations of the strange tattooed patches pricked onto his arm while he was a captive of what they both call backbiters, former doctors now “a-hunting” human blood. Why they’re doing so remains initially unclear, although Kit occasionally breaks away from personal obsessing to deliver treatises on how humankind has reached “the end of days” because science has lost the battle against devouring bacteria that attack not only people, but, more disastrously, plastic. Meanwhile, Kit’s happy on the island and drawing closer to Crevan. Then a half-dead woman shows up to disrupt, possibly infect Kit and Crevan’s uneasy paradise, and Kit discovers she’s willing to do almost anything to survive. Although Calder missteps with an unfortunate last plot twist into psychological melodrama, the bulk of her novel plays cleverly with contagion and bacteria as metaphors for the spread of both good and evil.

Tantalizing prose carries what is essentially a cautionary tale about unintended consequences; Calder is worth watching.
