An outstanding romance, a great plot, great characters. The title is misleading, it's not my idea of an arranged marriage, it's more like an accidental marriage.
Setup: Lord Blakeney returns to London after a two-year absence to enjoy himself, but his parents require his attendance at a come-out ball for Minerva Montrose. A delicate incidents occurs which requires marriage between Lord Blakeney and Minerva. The bulk of the book is about what happens after their marriage, but I don't want to spoil the many excellent surprises.
A great romance about how love can develop even with a very bad start.
