Zeynep Cevik It definitely does and OMG the 2nd book was just, I think I'm going to cry, it was too cute. I finished the whole series in 4 days. I am going to read it again.
Alex Shrugged Although book 1 can stand on it's own, the rest of the books in the series are building up to something. It seems to start at the end of Book 1 in the last few pages and goes on from there. So... yes. Read all the previous books.
Kaitlynn Mino Yes it does matter because you might not know what is happening and you might miss some important events that are going on.
America Yes, everything that goes on is based on before. You wouldn't read harry potter out of order so don't read this out of order.
