Overall I quite liked this book. It gives a pretty balanced overview of the current state of synthetic biology (future possibilities, history, international orgs and stances, the United States involvement, potential solutions, etc). Some of the major improvements in the field that the author would like to see (in terms of safety) are; increasing the United States position in synthetic biology -- in part to boost the economy and in part to be involved with figuring out the governance of cutting edge technologies, correcting for the mass anti GMO movement which has decelerated synthetic biology research (mostly abroad but it is starting to also affect the United States), putting in place national and international guidelines for research, and in general doing more to facilitate cooperation and cross talk between people in the field.
She mentions many other ways safety could be bolstered, but makes the point that 'feasible alternatives to self-governance are limited when technologies are still in the early stages of development, particularly when the applications are of broad interest, generating funding from private companies and multiple national governments, when the work is pursued in many places internationally, and when the technologies have great potential for tangible benefits to health and medicine.' In this vein, a large part of the suggestions are self-governance based. I am sympathetic to this stance.
I gave it three stars because I found it repetitive and some parts seemed lengthier than necessary. It had a ton of good information though, and I learned quite a few things I hadn't thought about prior to reading. I'd recommend to anyone trying to get a landscape view of synthetic biology from the pov of biosecurity.
