We recently have had a hard time getting the boys to go to sleep at night. So, in my mind, the solution was to totally skip naptime! Well, I don't think this little boy likes this idea too much. 
The last two days, he's put himself down for a nap ... granted, it's on the couch (or the laundry), but it's still a nap.
Do you remember this picture? Yeah, I guess he can fall asleep anywhere. That's something he got from his dad.

We've gone back and forth with Marian (our 5 year-old) with naps...We have her stay in the family room while the other two sleep in their beds and usually she ends up falling asleep for about an hour or so. We thought she was completely done with naps, but she takes one nearly every day and still sleeps well at night...Tricky stuff, those naps!!
Oh and I think Fablehaven would be good for a 3rd grade level as well as the Spiderwick Chronicles. I didn't know if you noticed my friends comments about the books on my blog answering your question. But I too agree with them they would both be good picks!
