Need Book Suggestions!?

ok so since the summer is almost here.. that means a lot of reading!!! i need suggestions on some books i need to read. I LOVE romance stuff... so any kind of romance i would like. and i love suspenseful/murder mystery books. DON'T SUGGEST TWILIGHT OR HARRY POTTER (Ive already read those). I love Agatha Christie and Mary Higgins Clark so please suggest other book besides those authors because i already read their books.
