“The main elements of Farnsworth’s brilliant second thriller featuring the man known as John Smith would individually be enough to sustain interest; the combination of a telepathic lead and a terrifyingly plausible effort to use the Internet for social manipulation produces intelligent and knuckle-biting suspense… Farnsworth credibly ups the ante for his hero and makes accepting his paranormal abilities easy. Many will want to read this novel in one sitting.”

Booklist gave FLASHMOB an excellent review as well. (Not online yet, but here's the highlights.)
"Farnsworth is a genuinely gifted storyteller, able to take a fantastic premise and build onto it a story that feels not just plausible but completely natural... A fine genre-bender."
Kirkus Reviews also had some kind words for FLASHMOB:
"A smooth, assured effort... another entertaining performance by Farnsworth, who brings an edgy sense of humor to the proceedings."
