is book #1009 of the Heartsong Presents line.
==Book Description==
For the past few years, Emily Madden has devoted her life to her work as a nurse at St. Jude Children's Research Hospital--partly as a way to lessen her grief over losing her sister to childhood cancer. Love isn't on her agenda. But after she meets Andrew Beckett, the uncle of her favorite patient, she's surprised by how much she enjoys his company.
Andrew isn't in Tennessee for love. He's there to help his niece fight a hard battle against the cancer raging through her. Then he meets Emily and can't seem to keep from thinking of her. 
As Emily and Andrew's friendship grows into something more, can they find the courage to face what holds them back? Will Andrew be able to forgive himself for a past tragedy and accept forgiveness and love? And will Emily allow herself to let go of a long-held quest to fulfill her sister's dreams and chase the dreams of her own heart?
