From Wakefield and Towton: the Wars of the Roses by Philip A. Haigh
The Wars of the Roses was a complicated, bloody affair between the houses of Lancaster and York, and witnessed much changing of sides. That disjointed feuding persisted for a staggering thirty years and was a north versus south affair. However, the period and conflicts covered by this title are refreshingly clear. An intriguing tale of treachery and deceit.
