New Duets-at least to me!

So two students of mine were ready for some new duet books and I felt more contemporary music would be more to their liking.  I emailed FluteWorld and they gave me some suggestions.  I ordered some of them.  I was hesitant to order one of the books because of the price (more than $20 after shipping) and not having seen the music to know for sure this is something my students would like.  I love the book!  It is a challenge for them, using many songs they have heard, in keys that are not just Bflat or Eflat.  Both of these students have completed Book 2 of Accent on Achievement and have been playing for 3-5 years.  The book I am in love with can be found here. I think I might buy the other duet book by the same arranger Fun Flute Duets. The people at Flute World were spot on when they recommended this book. I am so glad I contacted them.
