Hi! I've just started reading Ice Queen and I realised that in the summary her full name is Sasha Petrov. I don't know if you've changed this in the book but I just wanted to let you know that for Russian girls, their last names will usually end in -a. So Sasha's last name would be Petrova! Also Sasha in Russian is only a diminutive name, aka a nickname, for alexandr/a! Feel free to correct me if you intended for her name to be written the way it was!
