Mum Leila Neve was told by medics to say her final goodbyes to daughter Charlotte following an "extremely rare" brain haemorrhage.
Leila got into the hospital bed to give Charlotte her final cuddle when Adele's Rolling In The Deep came on the radio - a song the pair used to sing together.
Leila started singing it softly - and Charlotte began to smile. And two months later, she astonished doctors again by learning to walk and talk.
Charlotte was admitted to hospital after the haemorrhage caused extensive brain damage and left her unable to speak or see.
She had two operations to stop the bleeding on her brain but was left in a coma. But now she has gone back to school and is even taking dance classes.
"I climbed into her hospital bed to give her a cuddle - she was wired up to machines and unresponsive - and Adele came on the radio.
"I started singing it to her because she loves her and we used to sing that song together.
Charlotte started smiling and I couldn't believe it. It was the first time she had reacted to anything since the haemorrhage. The nurses were astounded and told me to keep singing - and she smiled again.
"The nurses said it was like I unlocked her and from that day she started getting better and better."
She added: "Charlotte has been brilliant. She is so determined and brave. The doctors have stopped telling us what she should be able to do - because she has amazed them so much.
"From the scans, she shouldn't even be able to walk again - never mind talk, ride her bike and run around like she has been doing.
"She went back to school about two weeks ago for one hour a day and still has her occupation therapy and speech therapy, which is helping.
"She's gone back to dance class now where she does street, ballet and tap which she loves, although it really tires her out now.
"Music is a big part of her life - she loves music. She loves singing and dancing along to Adele, Katy Perry and Pink. So it shouldn't surprise me that Adele was the song that woke her up. She's a miracle marvel."
