PROBLEM: Review: Most of the characters were annoying in this book. I do like how each one got a chance to tell "their" side of the story.Not one of her best but still made for a pleasent read. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: There are plenty of tension rods out there. The _only_ advantage of the Umbra rods is that they look better. (Why other manufacturers haven't figured out the design part is anybody's guess.) The problem with the Umbra rods -- all of them -- is NO tension. I have tried these repeatedly.... Why? Because my local hardware store carries them, and they are readily available elsewhere, and I have opted for form over function. Every single Umbra rod I have used fails drastically. They simply cannot bear any weight. Or, to put it differently, they cannot exert enough force against the surfaces they extend out to for them to bear any load. Worse, the springs that are the key element in sustaining the tension tend to fail. When those springs fail, anything you have suspended by the rod will come down. If it's a lightweight drapery panel, you may be in luck. Otherwise, forget about it. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: The story is a very simple one but the action, so to speak, doesn't really happen until the final third of the book. It was a battle to get through the dry middle!Unfortunately the story is also exceptionally easy to guessand the turns of the story are not surprising in the least.On the plus side, the book gives a good glimpse at life in Puritan early American communities and their moral strucutres. 
 Polarity: Negative

SOLUTION:
True
