Ethan Gage wants to enjoy the fruits of victory after helping Napoleon win the Battle of Marengo, but an ill-advised tryst with Bonaparte's married sister has made that impossible. So now, with President Thomas Jefferson's blessings, Ethan and a mystic Norwegian, Magnus Bloodhammer, embark upon an expedition into America's western wilderness--dodging hostile Indians and a British seductress as they search for the mythical hammer of the Norse god Thor. The prize, which was allegedly carried to North America more than a century before Columbus arrived, leads them across a landscape no white man has yet traversed. Here Gage's skills will be tested as never before--as he braves frontier peril en route to the most incredible discovery of all time.

In deepest winter, beware the coldest hearts . . .

London, 1850. Constance Horton has disappeared and her sister Maude is determined to find out what’s happened.

She discovers that Constance has disguised herself as a boy and boarded a ship bound for the Arctic, but when the ship returns without her the truth about her fate is buried by sinister forces.

To find answers – and deliver justice for her sister – Maude must step into London’s dark underbelly, and into the path of dangerous, powerful men. The kind of men who seek their fortune in the city’s horrors, from the hangings at Newgate to the ghoulish waxworks of Madame Tussaud’s.

It is a perilous task. But Maude has dangerous skills of her own . . .
