The Dream Daughter by Diane Chamberlain

This would have been a sweet story about a mother desperate to save her unborn child from certain death due to a heart defect and her pains to make sure the child knows she loves her. You, dear reader, are in for a treat because as an added bonus this story has the added element of time travel for the mother to get the surgery that doesn't exist in her current time and then runs into logistical problems. The technology might make you wonder but the heartfelt problem and desire that every mother has for her child to be healthy and happy are all there. There are plenty of twists and complications galore for Carly but she follows her heart and hopes for the best. Great characters and a very unusual storyline will keep you glued to the very last page.
