I'm very behind on my YA reading since most of what I've been reading lately is for research, so unfortunately yet again I don't have a YA book recommendation.
But I will recommend one of the research books I'm in the middle of for anyone who is at all interested in naval history. It's called The War for all the Oceans by Roy Adkins and Lesley Adkins. It's the story of the British naval battles that took place between 1798 and 1812, and it's so exciting that it reads almost like a fiction book. If you enjoy that kind of book, check it out—it's a good one.
