The Painter's Daughter:

3 stars: updated rating
When I purchased the hardcover edition, I reread a lot of it for fun. I apparently read through it too fast to notice some content issues the first time... I was so interested in seeing how the plot would end that I didn't see how sensual many of the details were. Unless the hardcover is a different book than the paperback, which I don't think likely!

4.5 stars
This book was so hard to put down. It's Julie Klassen at her best, with intrigue, danger, and a young heroine dealing with her first broken heart.
When Wesley Overtree deceives Sophie into giving him everything and then rushes off in search of new things to paint, his brother Stephen comes right behind, trying to find him and bring him home to family duties. Thus Stephen finds Sophie just as she's realizing she's been deserted and left pregnant and unmarried.
Something about her face will not let Stephen go. He offers to marry her before he leaves for war, giving her a name for her child and a home with his family. Sophie has little choice, with an unwanted suitor her father likes or a ruined name as her only other choices.
Once Sophie comes to the family home, there's intrigue, secret passageways, and more. I loved Kate best and hated Wesley most. There's a conflicted soldier seeking to throw off his demons and move one, and a young lady who becomes Sophie's friend, and a mysterious old nurse of Stephen's who somehow knows all sorts of things.
Will Stephen return from battle and become a true husband? Or will Wesley return and convince her to follow her girlish infatuation with him instead?
