Masks of Scorpio(Dray Prescot

the long version

[Book 31 of The Dray Prescot series] For Dray Prescot, the task of burning out the cult of the Silver Leem had been given Star Lords priority. Although he was emperor of Vallia, still he had to work incognito on an enemy island until that task was done. Sided by his warrior daughter, Ros the Claw, and aided by a valiant crew of piratical swashbucklers, Dray invaded the capital of the secret order only to find treachery and terror where he had thought to find treasure and triumph. It became a battle of golden masks against silver masks--and behind each facepiece could be hiding the bony features of the Grim Reaper himself!
