Reader voices
The most-liked reviews on Hardcover (credited to their authors).
“Why was the book so convoluted? The caretaker's father just happened to be the old love interest of the paralyzed mute patient? The patient was actually the (not) dead sibling of the patient? Oh and she wasnt mute or paralyzed? Oh and the house is on a crumbling cliff? And the maid is the surprise granddaughter? Geez.”
“I finished this book in one sitting, I couldn't put it down. Lots of interesting twists. I enjoyed it and would recommend.”
“I was really enjoying this book until the end. Too many plot twists which made the ending cheesy. 2.5 stars.”
