Zack is not my favorite of the Cold Fury Books. While I like the tension and chemistry between Zack and Kate, Zack is a douche. I know, I know. He's grieving, give him some allowances. But I actually don't think grief is a get-out-of-jail-free card to treat people poorly and with great disrespect. I do however love Kate, who has great deal of spirit and personality, which makes up for Zack being a dick, mostly. And Ben is a little cutie-pie. I like Ryker's introduction and the bond he and Zack quickly form. Not the best of the bunch, but still a mostly solid read.
