Stealing Time by B. W. Haggart

Shackled and dressed in a neon orange jumpsuit, art thief Cassie Sinatore awaits extradition at Heathrow Airport. An accident with a nearby experimental radar plane throws Cassie back in time, dumping her in a wooded countryside. The rider who discovers her is charismatic, more compelling than any man she has ever met. She chalks up the man’s Regency outfit and odd behavior to the eccentricity of the rich. Or maybe he is just a nutbar, but the man is offering a ride. Lord Ross Kerrington, the new Earl of Drayton, having returned from the wars in 1815, finds the Kerrington family in turmoil, lunatic women who make him consider returning to the army. The alluring woman he discovers in the estate’s Greyfield Woods strikes him as equally mad. The woman wears bizarre attire, acting with a peculiar cheekiness that borders on insolence. Considering the very real dangers a madwoman faces encountering the surrounding inhabitants, he decides to bring her home to safety until he can decide what to do with her.

Unexpectedly, his family has other ideas. Faced with the realization she is trapped 200 years in the past, Cassie resolves to win her independence using her cat-burglar skills. Then things get complicated. Against her will, she finds herself caring about the Kerrington family, fighting a powerful attraction to the very proper Ross. Dependent on the Kerringtons’ good will, Cassie finds it increasingly difficult to navigate London society, the family, and even more, her growing passion for Ross.

Besides, someone is trying to kill him.

I read a lot of time travel novels. This was the best I’ve read in the last year by a country mile. Witty, wonderful characters (the matriarchal granny is more than a match for the heroine, Cassie, and that’s saying something). I loved the way slang separated by two centuries was interwoven through the story and I felt I lived this adventure, … I lost a whole working day to this book. Couldn’t put it down
