Plot Synopsis (as spoiler-free as I can get):
When Mackenzie is attacked and injured, Diego is there to subdue her attacker and provide aid to her. When he finds out that this is the 4th attack she has endured, he suggests hiring him as a bodyguard. Taking his advice, she hires him, and they begin investigating who is behind her attacks. When the evidence points to the employees at the foundation she inherited, Diego poses as her college friend who has come into money and is looking into starting his foundation. Mackenzie and Diego didn’t expect the intense attraction they had for each other. As the attacks continue and pick up, Diego needs to find out who is behind them and why. Mackenzie’s life is at stake, and he isn’t going to risk it. Will they find out who wants Mackenzie dead and why?
Main Characters
Mackenzie Stone: I liked Mackenzie. She was a little reserved for a character at the beginning of the book. But, once the author explained her backstory, I understood why she was so reserved. She had a horrible childhood. It also explained why her relationship with her family was so strained. Add in that she inherited the family’s foundation instead of her mother, and it became almost unbearable. She dealt with the attempts on her life pretty well (excluding that one scene where she drank Scotch and dry-humped Diego). I also liked how she dealt with her employees (including the unruly ones). But, her true strength showed at the end of the book. She dealt with everything (and I mean everything) like a boss. Her speech at the jail was spot on.
Diego Lopez: I liked Diego, but I wish the author had been more forthcoming with his background. I wouldn’t say I liked waiting until halfway through the book to find out who and what he was. Other than that, he was perfect for Mackenzie. Diego was very good at his job, and he gave Mackenzie excellent advice about looking into the foundation’s financial records (and the records of the list of suspect employees Mackenzie had). His actions and reactions at the end of the book were outstanding. I liked how he stood beside Mackenzie and supported her through everything.
My review:
Once Upon a Christmas was a great book to read. Its fast-moving, well-written storyline kept me glued to the book. I got invested in Mackenzie and Diego’s romance. Once Upon a Christmas is an excellent book for those who enjoy romantic suspense.
The main storyline centers around Mackenzie, Diego, the foundation, and the attacks on Mackenzie. The author didn’t hide who was behind the financial crimes (the embezzling). It was self-evident from how that person acted. But I had an issue figuring out who was behind Mackenzie’s attacks. I was surprised to find out who it was. That did take me by surprise. That was a neat twist the author put in at the end of the book.
The romance angle was well-written. I liked that Mackenzie and Diego fought their feelings until Chicago. There was a slip-up that involved Scotch and dry humping.
The mystery angle was terrific. As I stated above, I did figure out half the mystery (the embezzling part). But I was surprised by who was behind her attacks and why. It made sense when Mackenzie had that confrontation at the police station.
The end of Once Upon a Christmas was enjoyable. I liked how the author wrapped everything up. But she left me wondering if there would be a book 10.
Many thanks to Margaret Watson for allowing me to read and review Once Upon a Christmas. All opinions stated in this review are mine.
