You know when it comes to short stories, the shorter they are the more I love them, so to me this was a great collection. The stories themselves didn't overlap each other at all and had different themes, although most of them dealt with chance encounters and how those can really affect your life.
My favorite story was "The Reflection, Only Hers," which deals with Annabel Shay who runs away from home after her mother is seriously affected my a mental disorder. Knowing that she herself will probably get the same disease someday, Annabel runs away to see some of the world while she can. This story was really great and grabbed my attention.
If you're a fan of short stories, I'd definitely recommend this little book. It's not YA per say, but there are no adult themes.
