Pixies, elves and fairy books. Soldier books. Recommendations for 5 year olds.

[Goandplay]

I have 5 year old twins. Looking for really nice story books for bedtime about fairies, pixies etc for my DD.
Also looking for similar but war stories or soldier stories for my DS.

We really enjoy Mick Inkpen books but running out and would like to get them some books for Christmas.

The Faraway Tree books by Enid Blyton might be up their street. My son just turned 6 and he really enjoyed them.
