Jonathan Reid is a doctor with a particular interest and expertise in blood, giving his transformation into a vampire a splatter of dark irony. The caring helper of the sick and protector of the weak is still in him, but so is a ravenous monster with an all-consuming desire to drain the crimson, life-giving nectar from his patients’ bulging, fleshy necks. It’s a deliciously evil and original premise for a vampire story, and frequently forces you to make some genuinely tough decisions.
