Disappointing. I absolutely loved Blood of the Maple, so I was greatly looking forward to Throne of Oak, but it has none of the same sparkle.
The plot is disjointed and a lot of potentially interesting stuff either happens off page or isn't addressed at all, while the frankly boring attacks on Mina happen far too often. Ms Bell can bring the snarky humour, but a little of that goes a long way, and the humour here edged more into shrill hysteria.
The book suffers from being neither a light-hearted, adventurous romp, nor gritty, paranormal suspense. It also felt half-baked and in need of a lot more attention from both writer and editor.
