In the world today there are basically three views regarding creation:
1. On the one extreme is the view that there is no God, and that the world was created by natural causes. In this view, science holds the only answers. We must use our inquiring minds to learn the truth, and there is a constant search for better answers.
2. At the other extreme is the Young Earth Creations (YEC). They believe that all scriptures must be interpreted literally, and any science that contradicts a literal interpretation must be wrong, and they therefore dismiss all of science as incorrect, and attempt to define an alternative science where the speed of light changes.
3. There is the middle ground between these two. Proponents, such as Ross, take the view that the Bible is true, but that being men, our knowledge is never complete, and that therefore, while the Bible is never wrong, we must occasionally be flexible in changing our understanding of it. These people believe that God does not lie, and that therefore as we use science to learn about his creation, what we find will also be true, and consistent with his word. Therefore they attempt to reconcile science and the Bible, finding common ground in an old-earth creation (OEC) interpretation.
Typically YEC do not get along with either group, viewing both as the enemy. According to their view, you are forced to choose to accept the Bible according to their entirely literal reading, or you must reject the Bible entirely. Faced with this choice many thinking people are driven away from Christianity, or at least are forced to deal with cognitive dissonance - On Sunday the Bible is true and science is ignored, but the rest of the week science is true and the Bible is to be ignored.
By contrast there is typically more constructive dialogue and respect between the scientists and the OEC group. In the world today, most people believe that science is true. OEC provides an interpretation of the Bible that rconciles Science and the Bible. In my personal experience, when I attempt to evalgelize people with any level of scientific sophistication, they immediately prepare to attack and ridicule the YEC view. When I take the OEC perspective, they are always quite surprised to hear that the biblical account written 3000 years ago is consistent with science not discovered until recently. As a result, this book by Ross is an outstanding evangelical tool - it permits thinking people to be reached who reject YEC out of hand. This approach doesn't necessarily convert them, because in most cases their disrespect for YEC has led them to a hard-core atheistic view, but it does eliminate the major obstacle to their ultimate acceptance of the Bible.
Basically, in evaluting this book, you have to ask - does this book lay out its view is a clear, convincing way. The answer is that it does. I'm not here to attack or defend one of the views above, but I can tell you that as a scientist, I am delighted to read books like this which help to clarify that the Bible is consistent with Science. I can tell you that this book has reinforced my Christian beliefs, and that it has also been a powerful evangelical tool. I highly recommend it.
