I wanted to work my way through most of these assorted coffees before I posted my experience ... and I would bet that 60 to 70 percent of my cups have had bad, old, expired coffee! I have simply been pouring out most of the cups because of the awful taste. I will not order this again.

Another excellent book by this author. It's not morbid or icky-just states the facts. Great for young readers (I wouldn't go below 13 though, just because it's not ...oh...easy to read? Not because of subject matter, but because it is written in an adult voice...she doesn't dumb it down.) I am planning to buy several more for Christmas gifts.

Very Cute!! I got this to send to my mom for Mother's day. it has a slip in the side blank card to write your message on, if you dont want to write by the 'vase'. My only wish - that it was a little bigger :) but it is really cute.
