Sister by Rosamund Lupton

Originally published in 2010 by Piatkus Books.
Audiobook narrated by Juanita McMahon.

Both tear-jerking and spine-tingling, Sister provides an adrenaline rush that could cause a chill on the sunniest afternoon — which, perhaps, the friendly company of a sister or two (or, in a pinch, a brother) might help to dispel.

I found Sister to be a solid mystery story, and I liked the character development, particularly the relationship between the two sisters. On the other hand, I found the structure - the character Beatrice writing a letter to her dead sister Tess about giving testimony in the murder trial - distracting and sometimes confusing. I would still recommend the book, though, and I will be looking for more mysteries from Lupton in the future.
