My ds is a great reader but lately it's been difficult to find books he likes. Tends to start them then give up. He's read TONS of enid blyton, all of lemony snicket etc etc, and is a very competent reader but it's just finding something that will capture his imagination and have him reading under the blankets with a torch (like he used to do before the holidays even though it mad me cross at the time!). Any suggestions?
