Big Sky Brides is a 2-book series which follows sisters, Kaitlin Shuller and Sierra Shuller (McArthur) as they search for Happily Ever After in Marietta, Montana. (Characters from my other Montana Born novels appear as listed below).
Bride By Mistake was originally part of the Montana Born Brides continuity.
Suggested Reading Order:
(These books can all be read as standalones. Characters in books overlap, though few plot points do, so this is how the books happen sequentially, but any order should be easy to follow).
Bride By Mistake
Finally His Bride
Keep Me, Cowboy
Bride for Keeps
