Quite an adventure and very well researched - I learned a lot about the 1700s and the Grand Tour that privileged young men often took after they finished their schooling. I loved the queer representation and appreciated the insights on race and race relations at the time as one of the characters is bi-racial and we see him encounter racism in their journey.  It's a lot of fun, kind of a queer grown up version of Enola Holmes vibes too.  Lots of hijinks and pirates and adventures!  But again, throughout it all we get a bit of history with it.  I felt it was a touch too long but otherwise think it's a wonderful addition to YA historical fiction!
