A Stranger In The House by Shari Lapena
Oh I seriously need to know what happens next! This book is gripping and will hold you until the very end. The story follows Karen, her husband Tom and her best friend and neighbor Brigid. I don't want to spoil anything and it really is best to go into this book knowing very little but I will say it has everything you could ever want and more in a thriller. Karen gets into a car accident on the wrong side of town and gets amnesia. Everyone is asking "Why?" even the police. Especially when a dead body is found right near the area she was in. Don't even think you know how this will end because the ending will make you gasp in disbelief and want more! I will recommend this to everyone!
