Would he go for "read something from thebook basket" rather than a specific book? And can you just do 3 or 4 10 minute lessons over the day?
This is how I have "directed" him in what to read in the past - just having a stack of books I thought he'd like around. But last week, when I asked him to read from a specific book daily (a book he on his own decided he wanted to read and started himself, but started lacking the motivation to finish...only because it left him with less play time..) then it was an all out, I hate reading. So, usually, reading isn't the problem. He will usually read well past bedtime on his own accord. And usually, he will read the books I buy for him and leave around.
