Megan Jacobs always wished for a different heart. Her entire childhood was spent in and out of hospitals, sitting on the sidelines while her twin sister Crystal played all the sports, got all the guys, and had all the fun. But even a heart transplant three years ago wasn't enough to propel Megan's life forward. She's still working as a library aide and living with her parents in her small Minnesota hometown, dreaming of the adventure she plans to take "once she's well enough." Meanwhile, her sister is a successful architect with a handsome husband and the perfect life -- or so Megan thinks.
