A rival heir Book

SPOILERS

NELL who is queen of the Mary Sues lives with her Aunt . THE AUNT FROM HELL! Sorry but if Laura Matthews was going for the curmudgeon with the heart of gold she missed by a mile. Auntie was mean, nasty, cruel and self absorbed. She insults everyone she meets. She treats her niece like a servant. She goes to bath with the express purpose of embarrassing a man who jilted her 40 years ago. She intends to announce at an assembly that he jilted her and ran off with another woman. His recently deceased and much loved wife of 40 years. This was to bring disgrace to his honor. Oh, please. I'm surprised he didn't get a standing ovation. The woman was a total witch. (Not sure if you can use the B word on amazon)
What was Aunt Nasty's comeuppance for this? A niece who pledges eternal devotion and an ex fiancee who agrees to marry the old battle ax if she wants.

The niece has her own romance going but it was lukewarm and predictable.

The ending to the story was awkward and abrupt. However I would read a follow up book to this if it turns out the earl or whatever he was sobers up and dumps her again. Then winds up married to someone he'll be happy with .
