The Milkweed Triptych, beginning with Bitter Seeds, is Ian Tregillis’s most celebrated work. Set during and after World War II, the series imagines that Nazi scientists created battery-powered superhumans while British intelligence turned to blood magic and demonic pacts to fight back.

The series follows Raybould Marsh, a British spy caught between these two terrible forces. What begins as a war story becomes something stranger and darker as the consequences of bargaining with inhuman entities pile up across decades. The books have been praised for their moral complexity and their refusal to treat superpowers as simple wish fulfillment.
