If you have read any of the other half dozen or Tempe Brennan novels you will be familiar with the ground that this novel travels, or digs up as the case may be. Rather too familiar I might add.
I have previously enjoyed Reichs' other books in this series, but this one just didn't do much for me. The plot has become formulaic and predictable, Tempe finds old body, tries for a while to persuade police that it is a murder victim, succeeds, and her on/off relationship with the ruggedly handsome policeman Ryan is doing nothing but boring me now. If you couldn't see the relationship 'plot twist' coming from when it is first mentioned in the book, it's time to go back to reading picture books I'm afraid.
If you really enjoyed the other Tempe novels, then you might like this as well. I think it will be the last one that I read though, Reichs has hit upon a winning formula in terms of sales, and it looks like she's going to stick rigidly to it.
