Cross my heart and hope to spy #1

I just finished reading I'd tell you I love you but then I'd have to kill you, so how i am reading the sequel to that which is called cross my heart and hope to spy. In this book all cammie wants is peace in her life. Ever since she broke up with josh she has promised herself and her classmates that she wont put them in danger (since she did when she snuck around to see josh). In the first few chapters cammie josh visits the school and finally learns the truth about cammie. But what josh doesnt know is that he was giving a drink that makes you forget things so cammie is worried josh wont ever remember she even exists. So far in the book cammie is really striggling to keep her word and stay out of trouble.
