'The bond between siblings is unlike any other relationship. Who’s the Favourite? reminds us so wonderfully how powerful, complicated and important siblings are, even when one of you is no longer here. Sibling grief can be overlooked and under-appreciated, with many feeling like forgotten mourners. I’m delighted that this book shines a light on our stories and gives us a voice, too.' —Callum Fairhurst, Founder of Sibling Support

'Relatively podcaster Carr mixes research, cultural criticism, and personal anecdotes for this informative debut study of the complexities of sibling relationships… Carr keeps the pace brisk by leavening research-heavy passages with chatty, vivid anecdotes – both her own and those gleaned from her podcast. The result is a thought-provoking, expansive look at an important but understudied familial bond.' —Publisher's Weekly

'Interwoven with insights from her podcast guests, it offers a thought-provoking look at the ties that shape us.' —Psychologies
