Unexpected new direction in a growing series.
Unlike most series, Nuttall's "Learning Experience" universe has only minor character continuity, instead, roughly following the Stuart clan once per generation.
Enter Generation 3. Captain Hoshiko Stuart, grand-daughter of Solar Union founder Steve Stuart, is given command of a squadron sent to an area of the galaxy, 6 months from Earth. And finds herself faced with an expansionist and utterly merciless race waging a war of genocide. Not just battles, but politics both interstellar and military.
I will merely say that Capt. Stuart most definitely takes the Montrose Toast to heart, for good or for bad. I'm waiting for the next book in the series. Luckily, as it's Chris Nuttall, the hardest-working man in SF, I don't expect to be waiting for long....
