Archetypal English toff William "Liam" Barnes is in big trouble. He's borrowed money from Irish gangster Davey McGrath with one simple condition. Get a special prism from Matthew Luttrell - seducing Matthew if he has to - and bring it back. But the prism isn't with Matthew, and Liam makes a decision he can't undo, meaning he's twenty thousand pounds in debt to a vicious gangster and has no idea where to find the prism.
That is, until he meets stoic Irishman Jim Henvey, the real owner of the prism, who has a cruel demi-goddess of a mother on the warpath for him. Liam and Jim quickly find themselves tied up in each other's messes, and with more than just the mortal world out to get them, they must find their way out of a battle between dimensions and still have time to figure out their feelings for each other. Or will they just sink deeper into trouble?
