You'll enjoy the other Janette Oke books too. She has quite a few.
Other authors that I have also enjoyed are:
Lori Wick - any of hers are great
Roxanne Henke - also, any are good
Karen Kingsbury - these tend to be more current times, and story lines that can make you cry. (I don't read them while pregnant, as it is too much emotion for me.)
I had read the Janette Oke books so much that I ended up giving them away some time ago, as I knew them by heart... :) I gave away some others at the same time, and am pulling a blank at the authors names at the moment.
In the sci fi/fantasy genre - have you read the ones by L.E. Modesitt Jr.? I highly recommend those. Start with the Recluse books, I have really enjoyed those. :) (Not the same as the Janette Oke books AT ALL - but still really good!)
(If interested in buying the christian fiction, then www.christianbook.com is a good place. That said, libraries tend to have a good selection too, especially in the large print section. (I don't know why they are large print, but that is where they seem to end up!) )
Thanks for asking this question. You let me have a little vacation in my mind thinking back about some of the really good books I have read. :)
