[Title] A Transatlantic Tunnel, Hurrah! [Author] Harry Harrison [Rating] ★★★ [Year] 2000 [Read] 2011/05/25 [Review] 
Rather short, but a fast read - Victorian flavored but not unreadable like a lot of steampunk. Decent but not great alternate history. (To call it great, I’d want it to be harder alt history with more details about how a transatlantic tunnel could even work at all, wrapped into a more engrossing story.)
