I am soon to embark on my dream trip of a lifetime from New Zealand to New York City. I would love to reread a novel for young adults I read when I was 11/12, sadly I do not remember the title or author but it was about a group of young adults in NYC sent on some sort of scavenger hunt by their parents and it was the first time I encountered the word Serendipity. I felt that it was a Judy Blume novel and have checked all of her listed titles but am still struggling to find this book. If anyone remembers it any help would be greatlt appreciated! Not a lot to go on, I know!:o
