A deadly allergy to the sun, and a sport which involves jumping off skyscrapers - what at first glance may appear to be a work of science fiction, is actually Jacquelyn Mitchard's new teen novel What We Saw at Night. Allie Kim and her two best friends, Rob and Juliet, have a rare disease known as Xeroderma Pigmentosum. This is an inherited genetic disorder which manifests as an extreme sensitivity to ultraviolet light, and in some cases neurological complications. The three teens must spend their waking hours at night because exposure to the sun can be lethal. It is an isolated kind of existence that fosters a tight bind between the friends. When Juliet, the most adventurous of the trio decides to take up Parkour, her friends join her in learning this extreme sport which involves climbing, jumping, and tumbling between buildings. A dangerous sport during normal daylight hours, it takes on a new level of risk as they work to master the techniques at night.
During one evening of building jumping, the friends see something that changes everything. After landing a particularly difficult jump onto the balcony of an apartment building, they see what appears to be a murder. Tension develops as Allie and her friends have different ideas regarding what was actually witnessed. The tone of the novel takes on a sinister feeling as Allie tries to uncover if a young woman was actually killed at the hands of a man in the vacant apartment. Her inquiries have attracted the attention of someone who could prove to be even more deadly than her disease. Learn what life is like with Xeroderma, discover the exciting sport of Parkour, and relish What We Saw at Night.
