I'm not completely sure why I was so confused at the beginning of Collision, and stayed that way for a cool minute, since I've read the previous books in the Shattered Hearts series, but I was. I don't know, maybe it was too much information, too quickly, but it is what it is. This is Kris & Chase's story, and it was quite the emotional one once I got over my confusion. They had been friends for forever, and just when they took it out of the friend zone, and spent a super hot night together, he gets a job that he has to be travel for on the DL, but what she didn't realize is that he wouldn't be back for 8 years with no communication. So, Kris started to move on finally, then Chase came back, and now he wanted to explore what they had, but she's not having any of it, and frankly, I didn't blame her at all. In fact, I'm not sure that I would have ever forgiven him, since 8 years is a LONG time to be away with no word, no matter how potent the chemistry is. On top of all this angst, there is a suspenseful undertone, with danger stalking, well, someone and/or someones, and I can't tell you who, because it could be spoiler douchery. It definitely kept me on the edge of my seat with all the twists & turns that had the f-bombs twisting & turning as they were dropped loudly. Plus, an added bonus is that some of the characters from the previous books were present for the ride along. So if you want to know how it all pans out, you know one clicking is up next! HIGHLY HIGHLY HIGHLY RECOMMEND!
