Just finished Children of Strife by Adrian Tchaikovsky, book four of his Children of Time series. Magnificent, truly. Best one yet.
Now I'm finishing H.N. Turteltaub's Over the Wine Dark Sea, that I put down to read CoS. It's also magnificent so far. I really appreciate how Dan Carlin's Hardcore History podcast gave me an ancient seafaring primer that this book is really living up to.
