As with Frump's other book, this one is a detailed, gripping narrative account of the rescue of over thirty mariners from the hulk of the Fort Mercer after she broke in two off the coast of Massachusetts in 1952. Although the Pendleton rescue is also covered in some depth, the crux of the account is the small-boat rescue from the stern section of the Fort Mercer, and this is rendered in a clear and interesting manner.
I do think there could have been more digressions relevant to the main story. The author lays out why this was not the case, but I felt that there could have been further context, both before and after the incident (especially as its aftermath pertains directly to the reasons why unsafe vessels such as the Marine Electric were still in operation 3 decades later).
There were a few times that the narrative was a bit muddled or jumpy, such as when Bangs was first mentioned without an introduction, some of the dialogue (which could've used slightly more context at times), and the movements of the other rescue lifeboat piloted by Bangs during the incident.
These weren't major distractions, but they were noticeable.
Overall it was a quick, involving read, and it certainly gives a great and detailed overview of the events.
