You did it! We figured this one out! It is a truth universally acknowledged (by me for certain) that the Bitchery pretty much knows everything, and really, it's true. Scroll down to see the solution for this HaBO - and many thanks!

This HaBO is from Sharon, who is hoping to find this series:
I recently read a book (part of a series) in which the twin brother of the hero (or two brothers of the heroine) finds out that they are not fraternal twins, but half brothers. One was born within a few days of the other to the father’s mistress.
At end of book, the brothers move to another town. Their books were to be subsequent ones to that series. I think it ties to another series set in that second town.
It is probably a recent book because I think those books on the false twins weren’t yet out when I finished the other. Hope you can help.
This HaBO was sent to us earlier this year, if that helps with the timeframe.




Happily Inc. series by Susan Mallery. The “twin” brothers are Mathias Mitchell (Second chance girl) and Ronan Mitchell (Why not tonight)
This reminds me of a Lisa Kleypas series, but I can’t remember which.
I think you’re looking for “Thrill Me” by Susan Mallery. It’s about the eldest of 5 brothers, Del Mitchell. In the course of events, his baby brothers discover that they’re half-brothers rather than fraternal twins. Comment #1 mentions the books that ultimately feature the baby brothers.
@Dani I think you’re thinking of the first two in Kleypas’s Hathaways series. Not quite the same situation, but it jumped to my mind too.
The Happily Inc. series is on my wish list – any thoughts as to whether it should move onto by TBR list?

@JenniferH I highly recommend Susan Mallery’s Happily Inc series. If you haven’t read her Fool’s Gold series you might enjoy starting with it to understand her town building. I have fallen in love with both series and wait eagerly for any new books. As I said to my friend introducing the series to her, I feel like I know these people as friends. I have reread the books multiple times to visit with friends I fell in love with. Enjoy Susan Mallery’s books.
Penny Reid’s Winston Brothers series has this. It links to the Knitting in the City series.
Seconding Penny Reid’s Winston Brothers.
Recently read the books, they are part of the Happily Series by Susan Mallery.
” The Heir and the Spare” by Maya Rodale?
First time ever that I even have a relevant suggestion, much less a possibly correct answer, and, of course, it’s already been suggested.
