Hmm, not sure on what books are currently good for this either.
But I do like this website:
Understanding Evolution - Your one-stop source for information on evolution
It's very simple and pretty, with some great diagrams.
I'm still waiting for the "Children's Bedtime Evolutionary Biology" books to be written though
ABE: Also, if you want to ask questions (a method of learning which I consider to be the most effective), feel free to stop by this forum's chatroom when you see myself or any of the other 'science-oriented' members of this forum.
