The Hesperus Prophecy

Secret societies, the noble Clypeate and wicked Obturavi, battle to determine humanity's fate. Using knowledge and technology left behind by mythological gods, the Clypeate fight to protect humanity while the Obturavi wish to subjugate. When the Obturavi partner with Nazi Germany to build the ultimate weapon, the Clypeate's only hope of stopping them lies with an outsider, biology professor Declan Riordan. Fulfilling a prophecy handed down by George Washington, the professor must navigate a new reality where technology borders on magic, revelations abound, and mortal danger is ever-present.
