The Teacher is the newest release from Freida McFadden and overall it is another solid psychological thriller, in typical Frieda McFadden-style. 
I absolutely love the pacing of her books, it can make a 402 page book fly by and it's so difficult to put these books down. For me I was put off by the teacher/student relationship (obviously the point) but it was really difficult to read honestly, it was too gross. I do like the various POVs we get and trying to make out who is telling the truth and what is real. 
There was a major twist in the book which I thought was just too obvious and I could see it from a mile away, but there was a part in the epilogue that did completely baffle me. I'm always pretty impressed by the way Freida McFadden goes that extra step with a twist you don't see coming. 
2.5 stars
