I fully loved the first 80% of this story, particularly the excellent chemistry and tension between our overlooked and underestimated heroine and rakishly overconfident hero. This was set up as brother's best friend and my biggest disappointment was that it never fulfilled this plot set-up in the third act. The conclusion felt rushed and I struggled with some of the timing/decisions around intimacy, for how stressy they were. That said, I really enjoyed this book's set-up and with more time/resolution at the end, it would have felt a lot more balanced.
