Howling Dark

This is book 2 of the Suneater Series. Hadrian Marlowe continues to be tipped from one disaster to another. This time he's searching for links to the enemy from book #1 on a planet that nobody else believes actually exists, "it's only a myth" they say. And it's a big galaxy we live in. Things get very dark as this book proceeds and it left me reeling for days. I'm loving this series.

No spoilers here but the title of #1, Empire of Silence, seemed inappropriate to me as I read the book as Hadrian's Empire is very warlike. But towards the end something happens and the phrase appears for the only time in the book. But it's still a mystery. This second title, Howling Dark is the same. There seems to be no place where the title hits home until towards the end when the phrase appears for the only time. And with a bit of thought I realised it refers to the mystery of the first title. Now my mind is saying 'Ha, so is this a hint of where the whole series is pointing?"
