Book for a young 11yr old girl please.

dd (12) has always been an able, but reluctant reader so I'm happy for her to read books that are fairly unchallenging if it means that she enjoys them and will keep going to the end - she wouldn't read a lot of the above suggestions even though they're great for real bookworms (I love a lot of them and would have read them myself at that age).

She's another David Walliams fan and hopefully some of the books that she has enjoyed over the last year or 2 might suit your niece. These have included quite a few Jacqueline Wilson (particularly Lola Rose and the Bed and Breakfast Star), the Mr Gum series, The London Eye Mystery (Siobhan Dowd), A Series of Unfortunate Events (Lemony Snickett), Chitty Chitty Bang Bang Flies Again (Frank Cotterrill Boyce), Dear Scarlett (Fleur Hitchcock) and Are you there, God? It's me, Margaret (Judy Blume)

I was searching some useful reading books for my son and I started by googling and this uncovered a few valuable sites and blogs where I found list of books name and best of them are: A Bad Case Of Stripes & No Bullying Zone

Those Helen Forrester books are excellent. I remember reading them when I was about 11 too. I still have my copies :)

I'd also second the Family From One End Street books, as well as many of her (E Nesbitt) books - such as the Five Children and It series.

The Little House on the Prairie books are lovely - I've just had a re-read of all of mine!

Some other books I also enjoyed at that age:

My Family and Other Animals & The New Noah (both by Gerald Durrell)
Born Free/Living Free/Forever Free (by Joy Adamson)
The Dark Is Rising (Susan Cooper)
The Wolves of Willoughby Chase series (Joan Aiken)
The Cats of Seroster (Robert Westall)
The Snow Spider Trilogy (Jenny Nimmo) - some of her other books are also very good

Books that your daughter would probably love are those by Diana Wynn Jones. There's the Chrestomanci series and then many stand alone books too. They are all really excellent.

When Hitler stole White Rabbit by Judith Kerr. Older children's book from the author of the Tiger who came to Tea.
I loved the Chalet School books as a child, school plus adventures, and my daughters loved them too. The first one is The School at the Chalet. Cheap paperbacks on ebay.
Goodnight Mr Tom. Also very good film with John Hurt.

...Mr GumTree books.

Muddle Earth is good simple adventure story fun.
Family at One End Street is OK even for sensitive children.

My immature 10yo couldn't handle Percy Jackson either. But he coped with Jiggy McCue.

Cat Royale books, My History books, TinTin, Asterix, Jane Blonde, Sprite Sisters, Calvin & Hobbes (I never stop endorsing C+H).

The Hetty Feather books went down very well with both my 7 and 10 year old at the time DDs.

Why is Percy Jackson out? My 9yo dd swallowed them whole... Possibly even started them at 8... They are really very good?

My dd is 10 and mildly dyslexic, she is currently reading Enid Blyton's Malory Towers series and loving it, she also recently read Charlotte Sometimes. Jacqueline Wilson is also popular and her favourites are Lily Alone and The Butterfly Club.

She read a series last year called Charm Hall by Tabitha Black, I'm not sure if they may be a bit young but dd really enjoyed them.

There was a time when my daughter never read a book to the end. There just wasn't any interest. Then someone said, try the books by Helen Forester about her early childhood in Liverpool. Well I eventually bought all the books in the series every book was read and more since. I've just read on Wicki that Helen Forester died in 2011. I would liked to have thanked her for giving the gift of reading to my daughter. By the way one of her other books "Latchkey Kid" was on the GCSE syllabus.

Possibly too old fashioned

The borrowers
The secret garden
Ballet shoes
The wolves of Willoughby chase
Narnia series

Also for more modern try:
Holes
Cosmic
Millions
Boy in the striped pyjamas
Anything Michael Morpurgo
Jean Ure
Skellig
Super fudge

I came on to say Harry Potter but you could also try:
Roald Dahl- Matilda, James and the Giant Peach, The Witches.

Heidi

Narnia series

Have you tried reading a book that she might like? Seeing you read it might get her started.

I third swallows and amazons- I loved those books at her age. Total escapism.

Is the Redwall series too old for her? I think I read them at 12/13. I remember being quite obsessed with them.

The moomins books are fantastically imaginative with lots of adventure, I loved the Exploits of Moominpappa most of all. Lovely illustrations too.

Can you still get the Trebizon books by Anne Digby? My sisters and I loved them at that age. Boarding school type book with tennis thrown in !

The Swish of the Curtain
Has she read any Noel Streatfeild? I always preferred White Boots to Ballet Shoes, it was one of my very favourite reads and still is
Necklace of Raindrops
Try something like the Blue or Orange Fairy Books? They may be a bit daunting looking but the fact that they are short stories might help - something for her to dip into. Maybe get one from the library?

Try The Children of Green Knowe and The Dark is Rising series.

Goth Girl

Second Swallows and Amazons and Little White Horse.

Charm School by Anne Fine - it's about Bonnie who has to go to a summer school class while her Mum studies - Bonnie is aghast to find the only possible class is Charm School, a kind of beauty parade, girls have to look pretty and sing and dance. Bonnie undermines the whole thing, partly uninentionally, in a hilarious way!
Also Diana Wynne Jones - good magical adventure books - Dogsbody, The Power of Three, A Tale Of Time City.

Oh and to state the bleeding obvious...Harry Potter?

The Ottoline books are aimed quite a bit younger but they're so lovely.

DD has enjoyed the Murder Most Unladylike books.

The Percy Jackson books are incredibly narratively (is that a word?) strong in the adventure genre, very funny (though they're not "funny books") and with a certain amount of stealth education as well (Greek gods). I'd say they're a very good step on from David Walliams.

When you say she's "young", Is this a reading age, concentration or maturity of content thing? Could you read to her? - something like Ballet Shoes or The Hobbit.

How about the Emily Windsnap books by Liz Kessler? About a girl who is half-mermaid.
