The Anubis Gates 

Brendan Doyle, a specialist in the work of the early-nineteenth century poet William Ashbless, reluctantly accepts an invitation from a millionaire to act as a guide to time-travelling tourists. But while attending a lecture given by Samuel Taylor Coleridge in 1810, he becomes marooned in Regency London, where dark and dangerous forces know about the gates in time. Caught up in the intrigue between rival bands of beggars, pursued by Egyptian sorcerers, befriended by Coleridge, Doyle somehow survives. And learns more about the mysterious Ashbless than he could ever have imagined possible.

Nobody's Home: An Anubis Gates Story 

For the first time in his esteemed career, Tim Powers returns to the setting (and a central character) from his landmark time travel novel, The Anubis Gates.

Tracking the murderer of her fiancée through 19th century London's darkest warrens, Jacky Snapp has disguised herself as a boy -- but the disguise fails when, trying to save a girl from the ghost of her jealous husband, Jacky finds that she has made herself visible to the ghosts that cluster around the Thames. And one of them is the ghost of her fiancée, who was poisoned and physically transformed by his murderer but unwittingly shot dead by Jacky herself.

Jacky and the girl she rescued, united in the need to banish their pursuing ghosts, learn that their only hope is to flee upriver to the barge known as Nobody's Home -- where the exorcist whose name is Nobody charges an intolerable price.
