I has been a little while since I read the previous one in this series. I was happy to find that Mangum did a great job of reminding me of what happened in the last book without it being too obvious or overdone. I did like this book, but in some respects not as much as the others. This one seemed to meander a bit. It also seemed to struggle to stay within the confines of the rules of the world that exists, so new things can come up that contradict other previous statements and it's ok because they don't know everything about time travel yet. It did hold my interest but it took too long to come to the end.
