Brush of Wings

"Despite needing a heart transplant and against the advice of her doctor, Mary Catherine moves to Uganda to work at a new orphanage. Whatever time she has left, Mary Catherine wants to spend it helping children-- especially since there will be no children of her own. The only problem is Major League Baseball player Marcus Dillinger, the man she never meant to fall in love with. Neither Marcus nor Mary Catherine's other friends--Tyler Ames and Sami Dawson--know just how serious her heart condition is."--
