Piece of Cake: Without A Hitch Book Three - clean romance novels

Kari and John are in the midst of planning a second public wedding so that their families and friends can join their happiness, when things take a turn for the worse and John's mother, Evangeline, falls gravely ill. She has always been a stubborn, sturdy woman, capable of anything, but her sudden sickness seems to be more than even she can handle. All Evangeline ever wanted was to witness her son's marriage, and now it seems as if this might not be possible.
John and Kari realize that the only way Evangeline will die happy is if she is able to see the wedding. They try to postpone it, but she urges them to carry on with their matrimonial plans, telling them she does not believe she will be able to make it. Stressed and worried, John and Kari work day and night to find a way for John's mother to witness their marriage, while Evangeline grows more ill. Meanwhile, Kari experiences some troubles with her pregnancy, and begins to worry about whether or not John will be able to love another man's child.
Kari also begins to fear that having Mark's baby will only make her miss him so much that she will not be able to give John the love and joy that he deserves. Will everything work itself out into a happily ever after? Or are these two love birds doomed to a life of hardship and unhappiness?
