A Perfect Storm question

If you do like the series, pick up the Undercover Series as well. Alice's story is in the second book, but you will want to read book 1 to get an idea of these new characters.

They can be read out of sequence but I think would be so much better read in order since they follow the same group of characters. The main characters in the earlier books do pop in from time to time in the book and it was nice to know their background and what they were like/the relationships/etc.

Arizona/Spencer in A Perfect Storm were introduced in book 3 so you know a little about them going in but not too terribly much.
