The Manor is the sequence Crimson Love belongs to, and the second entry in a series is a useful vantage point: the world is built, the rules are set, and the author can get straight on with the story. What arrives is romantic suspense with money in it, set around a lavish resort where rivalries and buried scandals do most of the plotting.
Brynne Asher writes to a recognisable romance brief, with an age gap, a woman who has reason to keep moving, and a jewellery heist threaded through the courtship. We describe the books rather than the person, which is the honest limit of what we can support here.
