For thousands of years, Cross has wandered the earth, a mortal soul trapped in the undying body left behind by Christ. He's been a thief, a con man, a soldier, and a drunkard. He's fought as a slave in the Colosseum and as a knight at King Arthur's side. But now he must play the part of reluctant hero, as an angel comes to him for help finding the Mona Lisa - the real Mona Lisa that inspired the painting. Cross' quest takes him into a secret world within our own, populated by characters just as strange and wondrous as he is: gorgons and dead gods hidden away in museums; faeries that live in countryside pubs, trapping and enslaving unwary travellers; and super-rich collectors who trade magical artifacts among themselves. He's haunted by memories of Penelope, the only woman he truly loved, and he wants to avenge her death at the hands of his ancient enemy, Judas, a forgotten god from an ancient time. The angel promises to deliver Judas to Cross, but nothing is ever what it seems when Judas is involved, and when a group of renegade angels looking for a new holy war show up, things truly go to hell.

Something is rotten in the court of the faerie queen. A deadly spirit is killing off the faerie, and it has mysterious ties to Shakespeare’s play, Hamlet. The only one who can stop it is the immortal Cross, a charming rogue who also happens to be a drunk, a thief, and an angel killer. He is no friend of the faerie since they stole his daughter and made her one of their own. When it appears she may be the next victim of the haunting, though, he must race against time to save her. He encounters an eccentric and deadly cast of characters along the way: the real Witches of Macbeth, the undead playwright/demon hunter Christopher Marlowe, an eerie Alice from the Alice in Wonderland books, a deranged and magical scholar—and a very supernatural William Shakespeare. When Cross discovers a startling secret about the origins of "Hamlet" itself, he finds himself trapped in a ghost story even he may not be able to escape alive!
