Ever read a book so good it changed your life? Adele has. 

The Grammy-winning, chart-topping, Oscar-toting star from Tottenham recently effused to her 38.5 million followers about the impact that Glennon Doyle's book had on her through her Instagram account. 

"This book will shake your brain and make your soul scream," Adele posted in the caption of an image of the cover of Untamed: Stop Pleasing, Start Living. "It’s as if I just flew into my body for the very first time. Whew!

"Anyone who has any kind of capacity to truly let go and give into yourself with any kind of desire to hold on for dear life - Do it. Read it. Live it. Practice it. We are a lot! But we are meant to be a lot!"

It's sent Doyle's third book back into the headlines after its publication in March, when it debuted at number one in The New York Times' Bestseller list.

So what is it? Untamed is Doyle's third memoir (the previous two were similarly successful). The author, who is 43, first won a following through her Christian parenting blog, Momastery – now a thriving online community. But her subsequent confessionals about surviving infidelity, divorce and family life resonated considerably more widely and won her fans aorund the world. 

The first sentence of Untamed sets out a fairly good synopsis for the life events that unfurl the book: "Four years ago, married to the father of my three children, I fell in love with a woman.” But it goes on to examine and deconstruct the impact of the patriarchy on being a woman, in what American magazine Bustle called: "a triumphant call for women's empowerment from a woman whose story revolves around seizing happiness for herself, at great risk and for greater reward."

Footnote:

Adele's position on the longstanding debate over whether it's OK to write in books appears to be clear – she urged her fans: "Read this book and have a highlighter on hand to make notes because you’ll want to refer back to it trust me!"
