*I received this books through Goodreads First Reads Program in exchange for an unbiased review*
I really, really, wanted to enjoy this book. It is a historical fiction/fantasy set in a time period that I have not seen covered that often. I will say this, the book is well researched, in fact if this writer ever put out a history book I would definitively read it. The pacing feels more like it wants to be a history and not fiction, I felt that while nothing seems to happen the story's pacing manages to be very stilted. There are long stretches where we are given detailed descriptions of battle planning and setting details, and suddenly we are days in the future tackling an entirely different problem. It is a bit jarring.
And with that we come to my biggest complaint of the book, nothing happens. The first 20 pages deal with Erik Redbjorn, the titular 'main character' that the book description has us believe will be the focus. After that we meet the plot devise mirror which sends us back in time where we meet captain of the Varangian Guards, Leo Spartiates. Along with him we get our real villains the Mystic druid monks (posing as real monks of course) and Cernunnos, the druid god. I will say that I enjoyed seeing Cernunnos as a Cthulhu-esque unimaginable horror from another plane, Celtic gods make for some awesome villains because so little is recorded about them, what with the Celts mostly having oral traditions. After collecting some Berserkers and visiting an island of lost Spartans, one things leads to another and we finally have our climax...which amounts to nothing. Cernunnos is just knocked out of the dude he is possessing so there is no real victory. Back in the present day the Turks have captured the city and Erik is the main character again for the last two chapters. Again nothing happens, and yet the book manages to end on a rather unsatisfying cliff-hanger.
I will not say this book is bad, it has some serious pacing issues and the story seems to never go anywhere. I found the characters mostly pretty one note, but that one note was clear. I will say this book is the absence of good, I found myself struggling to finish it because it bored me.
