Piano Adventures Book 2

[reinvent]

Hi all,
Does anyone know some good pieces of music that would be similar and slightly more developed than "Storms on Saturn" in Faber's book 2?
 I have a student that does not like most of the pieces,
but loves this one.  Any suggestions on other pieces to buy that would help her?  
 This is built on some kind of mode - all whole steps - and has a very interesting sound.
