Ever read a book so good, you wish it had more chapters?

This morning, I finished reading the book Hidden, by Eve Kenin. This evening, I was thinking how I wanted to lie down and keep reading, and I was sad when I remembered that I'd finished the book. The author did a great job creating a believable futureworld with compelling characters. Hidden is mostly told from the point of view of Tatiana, a human with genetic enhancements that make her a superwarrior. She's already killed one evil genius. Now she's after two more, before they can implement a plan to kill thousands, if not millions of people. A loner by choice, she unwillingly teams up with Tristan, a seemingly capable warrior with secrets of his own. Dorchester Publishing describes the book as "action romance." I say it's one of the best science fiction or "futuristic" romances that I've ever read. It's the sequel to Driven, which I haven't read, but I'm definitely going to be picking up a copy and delving back into Kenin's dark futureworld known as the Waste.
