I'm just finishing up The Riddle of the Sands by Erskine Childers. It's a wonderful book with engaging characters and an absorbing, exciting storyline.
Two young Englishman, Davies and Carruthers explore the islands, sands and sholes of Germany's North Sea coast in Davis' small yacht, the Dulcibella. The sailing and geographical details in and of themselves make the tale enthralling, but there is much more to The Riddle of the Sands than a tale of daring seamanship. This is also a story of mystery, intrigue and romance.
