Dr. Alexander Matthews, a myth-obsessed professor, never expected his latest research trip to Greece would lead to actually becoming Hercules. 
After stumbling upon a cursed diary, Alexander wakes up in ancient Greece... only now he’s got bulging muscles, an olive-wood club, and a to-do list that includes slaying the Nemean Lion. 
His body is built for heroics, but his mind is still very much a coffee-fueled academic. Between dodging centaurs and managing way too many injuries, Alexander struggles to keep his cool.
With ancient monsters to fight, divine drama to dodge, and the constant realization that he's really bad at ancient Greek armor, Alexander must somehow survive Hercules' legendary labors — all while trying not to faint from pain... or embarrassment.
"So, about the Nemean Lion... any chance it just needs a hug?"

"Great," I muttered, brushing dirt from my clothes. "Just great." The name wasn't exactly reassuring, but at least it was better than certain death back in Paradise.
