Hades' Pet Hellhound

Book 9 in the Hopeless Heroes series that takes readers on fun adventures back to Ancient Greece! What the Hades? Tim's used to solo time-travel but now there's a 'friend' along for the ride. "I'll get you for this, Cinderella!" When things go south after some bird spotting, Tim has to avoid being burnt alive, eaten alive or dead alive. But the Underworld is full of dangers, and the local music isn't exactly lifting his spirits.
