Quite a short book, but it's not a huge topic. Oriented towards the forensic science arena in the USA, it doesn't offer any tips for internationalising its summaries, so the UK reader (such as myself) is left with little idea of the differences in the way the field is structured. That said, it does summarise the opportunities available for general criminalists, pathologists, toxicologists, crime scene managers and so on, and give rough salary, training estimates, brief job descriptions, along with example job advertisements for each section.
Not as useful as it could be for the international reader, but it does its job.
