Thanks for the response...my little guy reads at a 5th grade level but does not seem to have a "love" of reading yet...my husband and I both usually have a book glued to our hands most nights but DS6 usually only reads for information and not usually for pleasure. We do chapter books at night and he has gotten into several different series but many of them aren't "exciting" enough for him..a friend had recommended the 39 Clues series because they said that they revolve around solving puzzles/clues - which my DS loves to do. So we thought maybe this might spark him? He has enjoyed books that I loved as a kid - How to Eat Fried Worms, The Phantom Tollbooth...so we have been trying to find something new for him that might catch his fancy :-)
