Books in the Castle series

The tenth Nikki Heat novel, set in the universe of the Castle TV series.

The world of Domum is in turmoil as Lord Darius challenges to be king. Jon McKinney, against Liz`s wishes, volunteers to stay and help defend the kingdom of Horstruff. With the help of Gilbert, Sir Anthony and Council Madoc, Jon leads the battle to defeat Lord Darius.

An ISIS-style beheading of a journalist, carried out by a New York City group pledging fealty to that rogue state, becomes more than just another case for NYPD Captain Nikki Heat when the killers announce their next target: her husband, magazine writer Jameson Rook.

If New York Police captain Nikki Heat is acting like she's seen a ghost, it's for good reason. Her mother, Cynthia, presumed dead for seventeen years, has resurfaced-but the threat that made her go into hiding is as grave as ever.
