How to Blackmail a Highlander by Michelle McLean

Lady Alice Chivers is done being controlled by her family. On the run from an arranged marriage, she needs a strong Highlander to escape. Only Philip MacGregor insists on sending her back to her pampered life, so she’ll just have to blackmail him instead. But now they find themselves in an accidental marriage, and soon they’re both playing a role that feels like it was meant to be real.
Philip is cautious, in control, and in way over his head with his unexpected wife. She’s intense, spontaneous, and can’t follow an order to save her life. And he might be falling completely in love with her. However, her distractions endanger the lives of those he loves. Now he must somehow undo the damage that has been done, before his friends pay with their lives.
