A historical novel. Enjoyed the historical background, which, I think, was well researched. Great depiction of the various relationships, treatments, and contrasts, among the different groups such as knights versus Maltese, corsairs, Turkish warriors, the Maltese elite versus the common people, men versus women, slaves, etc. Just one example: only men were allowed to be treated in the 'infermeria', as if women did not matter. At the same time, women were allowed in the infermeria to do mundane chores like laundering the hospital bedding.
The way things were, was described through what happened to one family and their friends and acquaintances, which kept things interesting. The book is well written, with a few surprises along the way. However, I thought the ending was predictable, and there were some aspects that were quite unbelievable, such as Domenicus's recovery after a bullet went right through him, or rescuing Robert in the nick of time, or concluding that Augustine is still alive based only on the finding of the eight pointed cross.
All in all, I enjoyed reading the book and am looking forward to the next book in the trilogy.
