Five star review for latest of David Mark's Aector MacAvoy series, bought at a Book Flood event held at Moorforge Viking Settlement in Cumbria, appropriately enough against a background of wind and rain and thunder. 'Thunder", as following multiple flashes of lightning is how this book reads. I'd binge-read the entire series in anticipation of this, teased by the many hints of shady back story about the circumstances of McAvoy and Roisin's coming together. The gradual reveals - and there were several of them - piled tension high enough to turn knuckles white, thanks to the stuttering uncertainties as to whether - <i>this</i> time ... it might come good. As ever, the prose was similarly breath-taking.
