When Collateral came out I read a few pages and realized I had forgotten some things over time. So, I went back to the first book and started from the beginning. I’ve just finished this book and it’s one of my favorites in the series so far. You get much more from reading a book the second time around. If you want to put your head in a book and come up knowing you’re reading one of the best series around, check out Tier One series. I can’t suggest a better one.
