When one of Dr. Ripley Davis' patients dies, the deceased woman's distraught husband attacks her, ranting that Ripley, the head of radiation oncology, murdered his wife. Zachary Cage, the new radiation safety officer, takes the claim seriously. An investigation uncovers more deaths, and Zach must determine whether Ripley is dangerous or in danger herself. Jessica Andersen's plot is innovative, and the scientific content seems authentic. Occasionally though, Intensive Care (3) comes off as unintentionally farcical, with too much activity happening in broom closets and characters using terms like "red-hot bodies" to talk about patients who die of irradiation. Also, minor quibbles distract from the reading experience, like a character using a cellular phone in the hospital.
