Influx by Daniel Suarez
John Grady has invented a gravity mirror, basically a means of cancelling gravity. Before he can announce his discovery he and his team are swept up by a mysterious group, the BTC, whose goal is to prevent the discovery of inventions that would disrupt the status quo of the 20th Century. John quickly finds that the promises of the early 20th century of cold fusion, molecular medicine and artificial intelligence have been discovered but suppressed by this organization and must fight his way out of their prison and find a way to bring them down so that humanity can benefit.
An interesting premise, especially since I was just talking with someone on how it seems that there haven't been any ground breaking discoveries in the last 40-50 years, just improvements on existing technology. The book's flaw is that it does have a lot of science in it which can cause the average reader's eyes to glaze over.
