First, let me remind you to go and purchase Cold Vengeance, which came out today. I will be doing the same when I get off work, and I believe it will be full of awesomeness.
Second, in lieu of a teaser, I'm going to direct you to one of the best review/snark sites I've come across. Mark Reads is, like the book I plan to read, full of awesomeness. To further explain, I just read every review he wrote of Suzanne Collins' The Hunger Games. I'm reminded why I loved the series and why I cannot read it again. Sitting in a restaurant, surrounding by people, tears streaming down my face--and that's just from the review.
Mark also reads other things, such as Twilight, Harry Potter, etc. The reviews are on a chapter by chapter basis, and posted on a regular basis. Whether you're new to a series, or just looking to be reminded (such as myself), it's a great site.
And now--off to buy/read Cold Vengeance!
