Well, I powered through Digital Fortress. It's a Dan Brown book. Not really comparable to Cryptonomicon. It was an interesting book, and I prefer it to the Da Vinci Code. A couple of the twists were not as predictable as they were in Angels & Demons. For people that do not like Dan Brown, don't bother with this one, otherwise give it a go.
Up next Neal Stephenson's Baroque Cycle.
