A YOUNG MOTHER'S SELFLESS ACT OF KINDNESS TURNED TRAGEDY INTO TRIUMPH FOR A LITTLE GIRL... NOW, ABC'S "EXTREME MAKEOVER: HOME EDITION" HAS CHANGED THIS WOMAN'S LIFE -- AND HER FAMILY'S -- BY RENOVATING THEIR HOUSE

"Imbriani Family" - Just months after a young, divorced mother of two got involved with a blood drive, she received a call that her marrow matched that of a baby girl with leukemia. At the time, Brook Imbriani had no idea how her selfless donation would impact her own family's life, as well as the life of a sick child. But Brook turned a tragic situation into triumph, and appreciation for her generosity was shown when "Extreme Makeover: Home Edition" literally knocked the Imbriani's neglected house to the ground and transformed it into a dream home, airing SUNDAY, DECEMBER 5 (7:00-8:00 p.m., ET), on the ABC Television Network (Rebroadcast. OAD: 7/18/04)

When Brook moved back into her childhood home in San Bernardino, California, to help her disabled mother take care of her dying father, it was because she wanted to be closer to her family. Her dad was the proverbial handyman and took care of the home's upkeep. So when he passed away two years later, the house fell into disrepair. Brook went to work full time to help pay the bills while her mom watched her grandchildren during the day. Despite Brook's busy life, when she was notified that she was a bone marrow match for ailing ten-month-old Esmerelda Ramirez, she unhesitatingly took action to help save the little girl. She even took a week off of work without pay to recover from the transplant.

Esmerelda's parents had been praying and waiting for a match for their baby. Today Esmerelda is a healthy four-year-old and in complete remission. Her mother, Nancy, said, "If it weren't for God and our donor, our child wouldn't be alive today." The Ramirez family nominated Brook as their way of saying "thank you."

The Imbriani house underwent a dramatic transformation in just seven days -- where every single room, plus the exterior and landscaping, was made over. Meanwhile, the Imbriani's - Brook, 30, her children, six-year-old Trevor and nine-month-old Brooklyn, Brook's mom, Pam Mansker, Brook's sister, Summer, her husband, Brett, and their 15-month-old son, Tyler -- went on their first-ever family vacation to the Hilton Waikoloa Village on the big island of Hawaii.
