[senco-forum] reading books for y6 RA just 7

 I have alittle money to spend on reading books for 3 year 6 boys (2 of whom have just arrived) with Reading ages around 7. The one who has been with us since reception has made huge progress to get to this stage. He is severly dyslexic,and has ADHD,  but very intelligent. Progress is painfully slow, He has read all the wellington sq, fuzzbuzz bangers and mash, wildcats..that he can manage at the moment. We both need something new and inspiring! 
  I have looked at the Ann Arbour Titles which seem good value, but the RA is rather vague...Barrington stoke have some good titles, but they are expensive....can anybody recommend anything new?
  thanks
