Query: Mutation "Mutates" Into a Bad Book

Mutation, by Robin Cook, is a scientific novel which shares the same concept as Mary Shelley's Frankenstein. Similar to Frankenstein, Mutation has a far-fetched storyline. The plot loses its credibility when the reader finds out that VJ, a ten year old genetically engineered child, is constructing his own state-of-the-art laboratory. The funding for the laboratory is brought in through a Colombian drug operation. Overall, Mutation did not keep its reader captivated due to its inconceivable characters and overwhelming plot.
