If you’re interested in the Sutton Hoo burials and the history of the whole site, including a detailed examination of how the sites were excavated and when, this is definitely a good resource. If you’re more interested in the more spectacular finds at Sutton Hoo, i.e. the contents of Mound 1, then that isn’t the focus here and although there are lots of helpful illustrations and a fair number of colour pictures, it’s not all about treasure.
For me, as with a lot of archaeology books, I find myself wondering about some of the author’s assertions. For example, that over a century people would ‘undoubtedly’ remember who was buried in a particular place. I find myself pretty doubtful about that, especially in earlier times when generations were rather shorter than they are now.
Overall, though, there’s some interesting information and speculation here, and I’d say it’s worth reading.
