Twenty-year-old Taylor Schmidt arrives in New York seeking work and love. She finds employment through the Quid Pro Quo Employment Agency and shares an apartment with Todd. Todd starts to fall for Taylor and finds her secret journals. He starts to read them (of course without her knowledge) and becomes late for work because of this. He then loses his job because of his tardiness.

In Taylor's temporary job she meets an intriguing man, Asher Krug, with whom she falls in love. To her surprise she discovers he is a "hit man". Asher soon has recruited her to join him as a hit man targeting Taylor's former boss. Soon however Asher and Taylor break up but Taylor finds that she has become hooked on killing. Todd finds a passage in Taylor's journal saying that Taylor is going to kill him. When she returns to the apartment in a drunken state, Todd remembers the passage, confronts her, fearing for his life, and shoots her. His lawyer tries to take a plea but Todd begins to question his sanity with the suggestion that much of this never happened; that much was all a fantasy.

Totally Killer is an enjoyable satire thriller. It is a darkly hilarious rendering of New York in the early 90's. The characters are well drawn and typical of their time. The reader is given an excellent picture of the society of this time with the commentaries and bits of culture.
