I really enjoyed reading this, and I liked Emily as a character, though I wish she'd been a little more able to stand up for herself and the little boy in the first chapter, I felt when something so shocking is going on, you'd react a bit more strongly. She just sort of watched, until Jack turned up to save the day. The book can be quite disorientating at times, as you try to figure out exactly what is going on, and whether any of these things are related. Sometimes mystery novels leave you with a few too many clues and you start to unravel the ending before you get there, but with this one I honestly had no clue what was going on with the missing girls, and Jack was such an enigma.
I was engrossed until the very last page, and give The Sham the rating of FOUR STARS OUT OF FIVE!
