I was surprised that I really enjoyed this book, since this isn't the type of books that I normally read. The beginning was a bit boring, but then it became more interesting with the mystery of whose sending intimidating messages, with the huge twist at the end. The book portrays significant messages regarding the beauty of being different and relatable friendship struggles, along with a narrative voice (by Mallow) that any reader can connect with. This book was a quick and light-hearted read.

Proof, as if there were ever any doubts after the author's award winning debut novel, Shadow Jumper, that J.M. Forster gets right into the heart of stories featuring young people who just so happen to have health issues.

A mystery (someone knows Mallow's 'secret' but who?) but, for me, firstly a foremostly, a novel of discovery, of coming to terms with being you.

Bad Hair Days is a wonderful read but more than that its inspiring. Its main character, 14 year old Mallow, a revelation to all those who feel as if they don't fit in, that they too are different.

Marketed at an audience of 10 to 12 year olds, its a gripping, emotional, sensitively written read featuring so many issues including bullying, family, friendships, insecurity, all wrapped up in a story about a teenager who as well as dealing with all the 'usual' teenage angst is having to cope with the emotional (and practical) issues of having the hair loss condition, alopecia.

In short, its exactly the sort of thought provoking story that I'd encourage all children to read.

I feel slightly fraudulent reviewing a kids book - I’m not the target demographic, and I haven’t really read many in recent years so I don’t have an appreciation of the children’s books universe.

But I have recommended this book to my 12 year old daughter. It’s a fairly short book, and doesn’t fit into her preferred genres of long series, action, adventure and history. I am sure she will find it a very easy read and will race through it, and will almost certainly not feel it fits the bill of a mystery. It’s potentially a bit simplistic for her tastes - thinking about secondary school she’s read books as diverse as THUG, the Art of Being Normal and Turtles all the Way Down, but I’ve recommended it to her as it moves at a good pace and covers a topic which will make her think, and give her an insight into difference from a couple of perspectives. Summary for my family? It’s a filler with value.

This book is very good I love how the character is really insecure because of herself I think it is really cool how she and her grandmother share the same condition

This book has a serious case of bullying and the ending is quite sad

I'm definitely not the target audience for this book, but my partner has alopecia areata too, so I thought it'd be interesting to read a book about it. There was lots of teenage melodrama and characters inflating problems by hiding the truth, but it was worth it for the lovely speech at the end.

Mallow suffers from alopecia. Starting at a new school, only her best friend Trude knows her secret... but it appears that someone else does too when she begins to receive odd text messages. Mallow tries to work out who knows her secret, to keep it from spreading.

This is a lovely story about being different. As Mallow begins to accept herself the way she is, she grows in confidence and popularity.

I thought this book was pretty good 😌 but there were a few issues.

1: at the beginning it was a little boring but it did get a bit better

2: The mystery about who was sending the intimidating messages was fine but I knew by the second message it was those 2 girls but the mystery it self was pretty good

3: ……….


Thanks for taking the time to read this!

HAVE TO READ

Hey. This is a awesome book for teens who love mystery, friendship, and love. I chose a 5 star rating because it was just so exciting and and the girl (Mallow) in the book had so much bravery. I hope you have a awesome day and stay safe out there.
