Another one of Shiney's recommendations comes up trumps
. I read the kindle edition in one sitting today, I was that gripped. Imagine the woman from 50 First Dates wakes up in her forties, but she's not in a quirky romantic comedy with Adam Sandler, but trapped in a nightmare with a husband she doesn't know if she can trust or not...
(and let's forget, for the sake of argument, that waking up with Adam Sandler would be any less terrifying)
I urge you to give this one a go if you enjoy a good psychological thriller.
