Averi Ramsey and Taylor Benson play together in a waiting room filled with toys at East Tennessee Children's Hospital.
They've spent a lot of time there.
They're both being treated for leukemia.
"I just got sick one day and and mommy..." seven year old Averi remembered. "I went to my old doctor and they told me I had to come here."
A former patient, 12 year old Jenna McMillan, wrote a book called East Tennessee from A to Z. It commemorates the 75th anniversary of the hospital.
