I enjoyed the first book and Push Back definitely followed suit. Unlike some series where the first one hooks you in then you suffer through the remaining two, Disruption keeps delivering with a wide variety of interesting characters logically dealing with a very crappy situation. What’s helpful for me, is that Bob McDermott likes things that I like, whether it be shipping, the military, backpacking the Appalachian Trail, or figuring out how things would work in a Post Apocalyptic World. Bob has broad knowledge of many things, and he works this knowledge into his books in a way that makes them believable and realistic.
I’ve read this genre about six and seven times this year, and the Disruption Trilogy (Bob’s new name for the series), is a very strong second following the One Second After series. It’s possible that books two and three (when it’s released) may beat out the "After" series. Push Back definitely put it within reach.
Please don’t misunderstand my rating of 4 stars. In my scheme, 4 stars is a very good book certainly worth a credit. I reserve 5 stars for those books bordering on literary masterpieces, that have substance greater than the story itself. Bob is great author, but I think he’s happy writing dang good stories versus trying to win a Pulitzer. And these types of books are an important part of my library as well.
