Here's some books I have read recently (or not so recently) that I highly recommend to anyone:
Spook by Mary Roach: How science is trying to investigate the afterlife.
Stiff by Mary Roach: The curious "life" of cadavers...very interesting, never irreverent.
Suburban Safari by Hannah Holmes: The author spends a year in her yard, meeting all of the critters she shares the land with...(I have read this countless times and it's still hilarious).
Attracting Butterflies, Birds and other Wildlife by David Mizejewski, the guy from Backyard Habitat on Animal Planet: Isabelle found this for me at the library because it has a picture of a bluebird on the cover, and this is the book that started me on the wildlife habitat path.
A Short History of Nearly Everything by Bill Bryson: He usually does travel stories (which are shoot-milk-out-of-your-nose funny) but this is a book about how the universe,
planet, animals and humans got here. In fact, I recommend ANYTHING by Bill Bryson.
The Chronicles of Narnia by C.S. Lewis. I just read all these again, and now that I am an adult, knowing that these stories are Christian allegories, I got alot more out of them. (And I wanted to brush up for the upcoming movie.)
Harry Potter and the Half-Blood Prince by J.K. Rowling. What can I say about Harry Potter that hasn't already been said?
