PROBLEM: Review: I was looking for a Carbon Monoxide alarm that was reasonabally priced, and was glad to find this one on Amazon.The reviews on Amazon were why I purchased this one. I tested the alarm, which works well, and hope I never actually need it!!Thanks Amazon for having it!

PROBLEM: Review: I was pleasantly surprised to find this book so readable- even by modern standards it is a good read, although the language in parts is somewhat old-fashioned, archaic even ..... but if you can deal with that, this is a good bet for anyone who would like a tale of England in the late 1600's... love, adventure, and even a little humor too!
