Summer read-aloud recommendations?

Our summer is turning out a little bit too much like this:

 

 

My go-to solution is a read-aloud book, to at least save some part of the day we had rued.  Despite having written dozens of posts about good books for kids, I’m having a hard time finding something suitable.  My goal is just to have something pleasant and enjoyable to do together, and not necessarily to tick off any Indispensible Classics from our Well Rounded Children list.  (I save the list for reciting to myself in the middle of the night, so as to make sure I have something to feel guilty about.)

Any suggestions?  Adventure/humor would be best, something boys and girls would like.  Kids I’m targeting are ages 9-15, and I’m aiming for the higher end of that group.  In the past, they’ve enjoyed of course the Narnia books, LOTR, some George MacDonaldFreddy the Pig books, The Phantom Tollbooth, Robert Nye’s retelling of Beowulf, and Jack Tales.

I just started Alice in Wonderland, but we may ditch it, just because we’re all a little more familiar with it than I realized.

Help me!

EDITED TO ADD:
Oh, and if you have something to recommend, it would be very helpful if you could mention (a) the age range of the kids who enjoyed it, and (b) a little bit about the book – plot, tone, etc.  Thanks!
