Review title: A great book Product review: This book explained complex concepts about running in a very easy to understand way. When talking about hydration, soft-drinks, caffeine ingestion, it explained pros and cons in a very lucid way. Best feature of the book is the anecdotal stories of many inspiring 50+ runners. It's a great read and hard to put down. I am a fitness runner, not a competitive runner but this book talking about old competitive runners doesn't bother me at all. Even though I wasn't good at distance running when I was young I admired those who excelled. Understanding the mindset of elite master runners helps me plan my running career after 50. Some day I will race even though it's not my current goal.
Ans: increase

Review title: Excellent as always Product review: After pushing through book 1, I am completely enamored of this series. Having pushed through 4 books in a week, I have to say that I am only getting more and more excited about the story. Even though the character development is often weak (e.g., new developments are often based on chance versus real character development which feels like a cop out - in particular versus newer series like Game of Thrones). However, I am sucked in and hope the fun continues.

Review title: The worst of the bunch Product review: I can't believe I read the whole thing!. What a bore, when we got to what I thought would be exciting (the border crossing, or the kill attempt), each was about one page long. The pontification about the Catholic religion was misplaced. And to hear the hero Ryan whining endlessly about being away from home for a few nights, please!

Review title: Repulsive Product review: This has to have been one of the worst books I've read in years. The writing was difficult to follow. The subject matter was offensive, and didn't come off as remotely funny. I was totally repulsed by this book.
