Not my favorite of the Penny stories, but I do enjoy Henkes' picture books and readers.

I really enjoyed the book overall, but I agree with Nicole that it could be a little confusing at times to tell who was talking. Also, something about the phrase "Louis Leakey discovered them" on the flap of the cover really annoyed me. I don't know how else I would have phrased it, but seeing that a man "discovered" all these amazing female scientists really bothered me.

I enjoyed it, but I thought there were jumps in the action that were unclear.

I need to think more on this, now that I've read both books in the duet.
