This is one of my favorite DWJ's books. I remember buying this one vividly, or not buying it rather. I think I must have been between 10-11 years old, and had a huge stack of books I picked out during a rare trip to the huge bookstore downtown (yes, I'm old enough that big box bookstores were rare in my childhood). This was the only copy of Power of Three in the store, but the cover was becoming unglued the pages (still bound together) were falling out of the cover piece. The manager let me have it for free.

I think my favorite thing was the slow realization that the Giants were humans.
