Before I read, I wasn't sure about the "tycoon" part, but I do like hidden identity when done well and the author is a favourite for a few reasons including our shared preference for sweet, not at all "alpha male" romance heroes, so I didn't hesitate much. Now I can confirm that Tristan/Chris is a lovely man, perfect for Maddie even if meeting her while undercover was particularly unfortunate considering that her ex had turned out to be a con artist.
I loved how real Tristan actually was when talking to Maddie as Chris, and it was fun to watch them make a miniature Christmas village ready for display (the kind of thing that makes me wish there was a movie version so we could see instead of just imagine how cute it all looked).
