Honestly, even if it's not your genre, it's a neat book series.
If you restrict yourself to the "ryanverse" It's quite a read, the books clock in heavy, 400-500 pages.
I enjoyed the series, and how Ryan ends up president is INSANE.
Also the first crisis he has to deal with is a nationwide pandemic of ebola, caused by terrorists.
One thing I admire about Clancy's writing is the pace never feels slow, things are happening, and they're happening fast.
