Just when I thought this series couldn't get much better, along comes Fortress of Fury and proves me wrong. This one has it all - gruesome battle scenes, betrayal, bravery (and cowardice) and enough realism to make me believe I was actually living in the Dark Ages. Beobrand is still the greatest warrior in Albion (Britain) and is forced to prove it many times in this book. His skills are never more tested than when Mercian forces under Penda invade Bernicia and set siege at Bebbanberg. Faced with certain death, Beobrand and his gesithas turn to cunning, and luck, to turn the tide. The battle scenes in this series are particularly graphic. I cannot imagine what it must have been like to have been involved in a war during this period. Facing down a shield wall or awaiting the thundering charge of mounted warriors must have been terrifying. While this is a work of fiction, it is based on historical events and locations. This makes reading this series that much more interesting. The author ended this book with enough loose ends to guarantee at least one more book. I, for one, cannot wait.
