Query: Utopia plenty

First off, a prior reviewer had Mr. Preston confused with his brother. Richard Preston writes the germ warfare novels. Douglas Preston writes delightful novels like Jennie and Dinosaurs in the Attic. All that aside, this is a great novel- much in the vein of the Preston/Child novels that many, many people swear are the best in the business. Child has outdone himself in the details-- they make the park come alive in the reader's imagination. Definitely a hit!
