A nice review from Lois Tilton at Locus Online for “We Who Steal Faces“:
Flea is a spy for England’s Queen Elizabeth in her war against the Spanish, and an assassin is eliminating all his contacts in Europe, one by one. He is also a member of the Elect, a quasi-immortal and a shapeshifter whose magic allows him to assume the face of others. Now he is determined to save his agent in Venice by obtaining the legendary universal poison antidote of Mithridates.
A gondolier by trade, Mafeo had given me my first tour of the city by canal thirty years ago. I had grown fond of the young Venetian during our explorations, even more so after he tried to cut the strings of my purse at the end of the day.
But the antidote is in the possession of a much older, more powerful member of the Elect, who has reason not to trust Flea. And his enemy is older and more powerful still.
A compelling adventure through a deadly labyrinth designed by the original Minotaur, full of traps and treachery.
