Meet the Blackthorn Brothers—three unrepentant scoundrels infamous for being mad, bad and perilous to love.Who is the darkly handsome Don John "Black Jack" Blackthorn? With his air of mystery and menace, the whispers about him hint of highwayman or government agent or even dark prince. But no one knows what it is Black Jack does or how dangerous he can truly be. Now Jack's mentor has disappeared, and Jack must track him down before it's too late. His unlikely help: the man's daughter—the very woman Jack had once wooed and betrayed. Lady Tess Fonteneau knows more about the fine art of clandestine activities—and about the mysterious Mr. Blackthorn—than he realizes. As their journey leads them on the adventure of a lifetime, their reunion is fraught with passion, high-stakes danger and the one twist of fate Jack never saw coming .
Wow, what a way to end the series! All along Jack has been this dark, mysterious man who we know very little about, but in this book we got to see who the man was behind the mask, so to say. As the middle of three bastard sons of a Marquis, Jack leaves home and begins working for the Crown doing the dirty work not too many others could do. Here he is sent after the man who was his mentor and is met with the man's daughter, Tess who he once thought himself in love with. They end up working together to try to unravel the mystery of her father's disappearance and find that after four years apart their attraction for each other has only grown stronger. Along the way they learn quite a few secrets that impact the way they see everyone around them and each other.
I liked that we finally got to see Jack as a real person and that he wasn't the bad man his family thought he was. Tess was the right fit for him and her little surprise made him an even more approachable character. The action was just enough to keep it moving along and the romance was perfect. I wouldn't mind a spin-off series from this so I could see what's up with Will.
