The Milkweed Triptych

The Milkweed Triptych is a trilogy of alternate history novels set during and after World War II. The series consists of Bitter Seeds, The Coldest War, and Necessary Evil. In this version of history, Nazi Germany creates superhuman soldiers through science and technology, while British warlocks counter their power by making dark bargains with supernatural entities.

The story follows British spy Raybould Marsh, German warrior Klaus von Westarp, and British warlock Will Beauclerk as their paths repeatedly cross during key moments of the 20th century. Their personal struggles mirror larger questions about sacrifice, power, and the price of victory.
