Adalind Jane Fay and Skylar Lainne Barne. Two different people, but somehow the same. Negative meets positive, but which is which? Heart transplant failure has ruined the lives of Addie and Sky, denying them the wonders of life. They're living on borrowed time, at least until a new replacement heart is available. But living doesn't mean just surviving. They can finally feel what it's like to have a best friend. And for the first time they are more than just stained glass.
