Q: At the beginning of this review, I'm going to try and be as brief as possible, mainly because I don't want to give away anything important about the plot. The novel is narrated in first person, both by Harry himself, but also through a female character named Tess, who was conceived after having an affair with Harry.

A: Good Review

Q: When I first read the reviews about how good this heater was, i thought they were exaggerating. How good can a little space heater make?! Well let me tell you, it made everything hotter. Its like my room was more comfortable! Now, it's all because of the heater, nothing to do with me. I'm so happy...oh yeah and no burning smell. A must buy if you need something that makes your place warm.
