From the Power of the Matchmaker series:
The Reformer by Jaima Fixsen
Mary Buchanan has bigger worries than the radical journalist moving in next door who’s spoiling her father’s digestion: unrequited love for a footman, a fractious aunt, patiently awaiting her destiny…
Already she’s nearly eighteen. No sign of destiny yet, but Mary’s certain he’ll be handsome.
Then she meets the reformer, this Mr. Samuel Brown. Destiny is closer at hand than Mary has supposed—if she can just get Mr. Brown to realize it.
