"My dad's a birdman"...similar books?

[usernametaken]

DD is currently reading this book (by David Almond) and loving it. Having skimmed through it myself I have to agree, it really is a lovely book.

Has anyone got any recommendations of similar books?

Many thanks.

I should have added that I love David Almond as an author but his themes/storylines are too advanced for DD right now.
