I'm not one to care too much about grammar or spelling errors, usually because I don't notice them. For me to notice, it is pretty glaring and disruptive to my reading experience. Unfortunately, this was one of them. They were jarring to say the least. As stated in the description, these were secondary characters from the Special Forces series. I thought Vadim would make more of an appearance, given their closeness in SF, but he didn't appear at all. This wasn't a big deal, but I had to fit in what I remembered from SF here; I didn't want to read SF part again, I would then get sucked in and I just could not again. But he really wasn't necessary for me to enjoy the story.I really liked the evolution of their relationship (Matt and Hooch). I really liked how mature they became and how much they came to really rely on each other. I loved how Matt became what Hooch needed and wanted.
