Query: Page-turner from the Get Go!

Nerdy but cute graduate student cracks a code and then is pursued by a lovely young lady. Coincidence? We think not! Add serveral near death experiences and even the most blase will be suspicious. The hero of this well-thought-out story is smart, clever and just quirky enough to be believable. You will find yourself having to read "just a few more pages" even though you are too tired to keep your eyes open, this book is a real page-turner. I don't want this to be a spoiler, so I can't go any further in my plot description (but don't trust the girl), but let it suffice to say that you will find this book exciting and entertaining! A rip-roaring read!
